How do I describe the end behavior, determine if it's an odd or even degree, and the real number of zeros? Please help me.
Answer:
1. Even Degree
2. 6 zeros
Step-by-step explanation:
Determine if it’s an odd or even degree:—
- The graph is shown approach positive infinity when both sides of x-values, negative and positive, both approach their respective infinity sides.
To put it simply, see when both negative x-values and positive x-values approach their negative or positive infinity, the y-values will always be positive, even if negative x-values approach negative infinity.
For a polynomial function to be an even degree, it must satisfy the following:—
[tex]\displaystyle \large{ \lim_{x \to \pm \infty} f(x) = \infty}[/tex]
As an odd degree, either negative or positive x-values will approach positive infinity or negative infinity, depending on the function itself.
From the graph, we can say that the function is an even degree.
__________________________________________________________
Summary I
Even-Odd Degree
Even Degree, when both sides of x-value approach their respective infinity, y-value will always approach positive infinity.
Odd Degree, one side of y-value will approach positive infinity and another will approach negative infinity.
__________________________________________________________
Determine numbers of zeros:—
- We can determine numbers of zeros by examining x-axis and the graph. How many times does the graph intersect or pass through x-axis? Count and you should get 6 intercepts.
Therefore, there are 6 real solutions/zeros for this function/equation.
__________________________________________________________
Summary II
Determine zeros
To determine or check how many solutions or zeros do the graph/function/equation has, you can use the graph method. Simply count how many times does the graph pass through x-axis and x-intercepts are zeros.

which function is equivalent to y =5 (x+3 ^2) -8 ?
A) y = 5x^2 +30x +37
B) y=5x^2 + 6x - 2
C) y=5x^2 +30x +5
D) y= 5x^2 + 1
Answer: Below
Step-by-step explanation:
So we can start off by solving this equation.
(x + 3)² = x² + 6x + 9
5(x² + 6x + 9) = 5x² + 30x + 45
5x² + 30x + 45 - 8 = 5x² + 30x + 37
Going off of this, we can already see that A is our answer.

A plane is descending from an altitude of 8,000 feet. The plane
descends at a constant rate of 500 feet per minute.
Which function can be used to determine the height, H, of the plane
after m minutes?
The linear function that can be used to determine the height, H, of the plane after m minutes is given by:
H(m) = 8000 - 500m
What is a linear function?A linear function is modeled by:
[tex]y = mx + b[/tex]
In which:
m is the slope, which is the rate of change, that is, by how much y changes when x changes by 1.b is the y-intercept, which is the value of y when x = 0, and can also be interpreted as the initial value.In this problem:
The plane is descending from an altitude of 8,000 feet, hence the y-intercept is b = 8000.The plane descends at a constant rate of 500 feet per minute, hence the slope is of m = -500.Thus, the equation is:
H(m) = 8000 - 500m.

Suppose you roll a number cube. What is the probability that you roll a number greater than 1?
Answer:
Ok a cube has 6 sides and the choices are 1,2,3,4,5,6. As you can see you need to know the probability getting greater than 1. So 2,3,4,5,6 are greater so, the answer would be 5/6 into percentage around 83% of getting greater than 1.
Step-by-step explanation:
Ben is 4 times as old as Ishaan and is also 6 years older than Ishaan.
How old is Ben?
✪According to question:-
Ben is 6 years older than Ishaan
So :-
Ben age - Ishaan age = 6 yearsput supposed values
4x - x = 63x = 6x = 6 ÷ 3x = 6/3x = (2 × 3)/3x = 2/1x = 2Original Ages :-
Ishaan age = xIshaan age = 2 yearsBen age = 4xBen age = 4(2)Ben age 4 × 2Ben age = 8 years✪Verification :
1st condition:-
Ben age - Ishaan age = 6 yearsput original ages
8 - 2 = 66 = 6LHS=RHS
Hence verified !
Required answer :-Ben's age = 8 years

A manager at a shopping mall counts 244 males and n females as they enter the mall. The manager realizes that 25% of all males and 25% of all females are children. She writes the expression 0.25n + 61 to represent the number of children who enter the mall. Is the manager correct?
Answer:
Step-by-step explanation:
The manager is not correct in her calculation.
Step-by-step explanation:
There are 244 males and n females who entered the mall as the manager at the shopping mall counts.
If 25% of all males are children, then the number of male children are .
Again, the 25% of all female are children, then the number of female chilfren are .
Therefore, the total number of children will be (60 + 0.25n).
But the manager gives the number of children to be 0.25n + 61 who entered the mall.
So, the manager is not correct in that calculation. (Answer)

Answer:
53 degrees
Step-by-step explanation:
because its at a right angle and measure 1 is 37 so 90-37 would equal 53
Step-by-step explanation:
because it is on a corner the hole corner = 90
1 + 2 = corner so
1+ 2 = 90
1 is 37
37 + 2 = 90
rearrange
90 - 37 = 2
so 2 = ???
If f(x) = 2(18 – 9x) + 4x, what is the value of f(7)?
Answer:
-62
Step-by-step explanation:
f(x)=2(18-9x)+4x
f(7)=2(18-9(7))+4(7)
f(7)=2(18-63)+28
f(7)=2(-45)+28
f(7)=-90+28
f(7)=-62
Answer:
f(7) = -62
Step-by-step explanation:
Basically, what the question is asking us to do is to plug in 7 every time we see an x.
f(x) = 2(18 - 9x) + 4x
f(7) = 2(18 - 9(7)) + 4(7)
f(7) = 2(18-63) + 28
f(7) = 2(-45) + 28
f(7) = -90 + 28
f(7) = -62

Find the co-ordinate of the point where y-4x=1 crosses the y-axis
Answer: (0,1)
Step-by-step explanation:
When a line crosses the y-axis, the x-coordinate must equal to 0.
Now we can plug in x = 0 into the equation given:
y - 4*0 = 1
y- 0 = 1
y = 1
Therefore, the point where the line crosses the y-axis is (0,1)

Answer: [tex]\frac{2x^2+s^2}{x(x+s)}[/tex]
This is the fraction of 2x^2+s^2 all over x(x+s)
==============================================
Explanation:
Currently the denominators are not the same, so we cannot subtract the fractions just yet.
We need to get the denominators equal to the LCD (lowest common denominator).
In this case, the LCD is x(x+s). Often the LCD is the product of the denominators, but not always.
To get the first fraction to have the LCD, we multiply top and bottom by x.
[tex]\frac{3x}{x+s} = \frac{x*3x}{x(x+s)} = \frac{3x^2}{x(x+s)}[/tex]
To get the second fraction to have the LCD, we multiply top and bottom by x+s
[tex]\frac{x-s}{x} = \frac{(x+s)(x-s)}{x(x+s)} = \frac{x^2-s^2}{x(x+s)}[/tex]
I used the difference of squares rule to go from (x+s)(x-s) to x^2-s^2.
-----------------------------------------
At this point, we have x(x+s) in both denominators and we can subtract
[tex]\frac{3x}{x+s} - \frac{x-s}{x}\\\\\frac{3x^2}{x(x+s)} - \frac{x^2-s^2}{x(x+s)}\\\\\frac{3x^2-(x^2-s^2)}{x(x+s)}\\\\\frac{3x^2-x^2+s^2}{x(x+s)}\\\\\frac{2x^2+s^2}{x(x+s)}\\\\[/tex]
Optionally, you can distribute the x through in the denominator, but I'll leave it factored.
