The graph of f(x) = x in a straight line passing through the origin (0,0) and  at an angle of 45 degrees to the x axis. It increases from left to right.

Reflection in the x axis  will convert all positive values of f(x) to negative values of f(x)  and vice versa.  

g(x)  = - x     and is a striaght line passing through origin  at angle of 45 degrees but the slope descends from left to right.

The reflection of function f(x) = x² across the x-axis is given by,

g(x) = -(x - 0)² + 0.

Use the concept of fucntion defined as:

A relation between a collection of inputs and outputs is known as a function. A function is, to put it simply, a relationship between inputs in which each input is connected to precisely one output.

Given that,

Function: f(x) = x²

Desired reflection function: g(x)

Reflection of f(x) across the x-axis gives g(x)

Need to find g(x) in the form a(x - h)² + k, where a, h, and k are integers.

To find the reflection across the x-axis of the function f(x) = x²,

Negate the function's y-values.

So, for g(x), the reflection of f(x) across the x-axis,

g(x) = -f(x)

g(x) = -x²

To write this in vertex form, complete the square. Let's begin:

g(x) = -x²

g(x) = - (x²)

g(x) = -1 (x²)

Now, to complete the square,

Take half of the coefficient of x, square it, and add it inside the parentheses:

g(x) = -1(x²)

Taking half of the coefficient of x, we get -1/2.

Squaring it gives 1/4.

Adding this inside the parentheses, we have:

g(x) = -1(x² + 1/4)

To maintain symmetry,

Write the expression inside the parentheses as a perfect square:

g(x) = -1(x² + 1/4)

g(x) = -1(x²  + (1/2)²)

Now, factoring out the -1, we get:

g(x) = -(x²+ (1/2)²)

Finally, we can rewrite this expression in the form a(x - h)² + k:

g(x) = -(x - 0)² + 0

Hence, the reflection of f(x) = x² across the x-axis is given by,

g(x) = -(x - 0)² + 0.

Answer:

1 1/4

Step-by-step explanation:

5/4 = 1.25

As you can see 1 is the whole

1 divide by .25 = 4

Thus, 1 1/4

[tex]\frac{5}{4}=1\frac{1}{4}[/tex]

~Learn with Lenvy~

1.25 is the quotient when 5 is divided by 4.

A division is a process of splitting a specific amount into equal parts.

In division, the dividend( the number being divided) is divided by the divisor (the number you are dividing by) to get the quotient (the result of the division).

In this case, the dividend is 5 and the divisor is 4.

So, 5 divided by 4 is equal to 1.25:

Five divided by four equal to one point two five.

5 ÷ 4 = 1.25

Hence, 1.25 is the quotient when 5 is divided by 4.

Answer:

The option which is:

On a coordinate plane, a parabola opens up. It goes through (2, 10), has a vertex at (5, 1), and goes through (8, 10).

Step-by-step explanation:

At first we should know the rules of translation

1) {f(x) + a} is f(x) shifted up (a) units

2) {f(x) – a} is f(x) shifted down (a) units

3) {f(x + a)} is f(x) shifted left (a) units.

4) {f(x – a)} is f(x) shifted right (a) units.

Given:

f(x) = x²

g(x) = (x-5)² + 1

By comparing [ the translation from f(x) to g(x) ] with the rules of translation

We can deduce that g(x) is the image of f(x) by translation 5 units right and 1 unit up ( rules 1 and 4)

See the attached figure which represent the graph of f(x) and g(x)

As shown g(x) goes through (2, 10), has a vertex at (5, 1), and goes through (8, 10)

By using what we know about intersecting lines, we will see that:

When two lines intersect, 4 angles are formed. There are two properties that these angles have.

a) We know that ∡5 = 47°

And 7 is not adjacent to 5, then 7 has the same measure:

∡7 = 47°

b) 6 and 5 are adjacent, then we must have that:

∡5 + ∡6 = 180°

47° + (2x - 5)° = 180°

That is the equation we need to solve to get the value of x.

c) To solve the linear equation we need to isolate x, let's do that:

47° + (2x - 5)° = 180°

(2x - 5)° = 180° - 47° = 133°

2x - 5 = 133

2x = 133 + 5 = 138

x = 138/2 = 69.

Step-by-step explanation:

A(x+1)³ + B(x+1)² + Cx + 22 =

A(x³ + 3x² + 3x + 1) + B(x² + 2x + 1) + Cx + 22 =

Ax³ + (3A + B)x² + (3A + 2B + C)x + (A + B + 22) =

2x³ + 5x² + 7x + 23

→

A = 2

3A + B = 5 → 3(2) + B = 5 → B = 5 - 6 → B = -1

3A + 2B + C = 7 → 3(2) + 2(-1) + C = 7 → C = 7 - 6 + 2 →

C = 3

remainder :

(2x³ + 5x² + 7x + 23 )/ (x² + 2x + 1) =

(2x³ + 5x² + 7x + 23 )/ (x + 1)²

Step-by-step explanation:

The ratio of students that got A to students that got B is an illustration of comparison

The number of students that got A in the test is 8y/x

The ratio of the student is given as:

A : B = y : x

8 students got B in their final test.

So, the ratio becomes

A : 8 = y : x

Express the ratio as a fraction

[tex]\frac A8 = \frac yx[/tex]

Multiply both sides by 8

[tex]A = \frac{8y}x[/tex]

The representation of the value of stock in dollars after 1940 is given as

V(t) = $1.25(1 + 0.07)^t.

The growing exponential can be written generally as f(x) = N(1 + r)ˣ, where N is the initial value and r is the rate of growth.

To find the expression different values of x and f(x) should be known.

Given that,

The value of the stock in 1940 is $1.25.

And, its rate of growth per year is 7%.

The general expression for the growing exponential can be written as,

f(x) = N(1 + r)ˣ

The given data shows N = 1.25 and r = 7/100 = 0.07.

Thus, the required expression can be written as,

V(t) = 1.25(1 + 0.07)^t

Hence, the required expression for representing the value of the stock V(t), in dollars, t years after 1940 is V(t) = $1.25(1 + 0.07)^t.
