find the quadratic function for f(x) = ax2 + bx +c and a=1, b=4, c= 3

Answers

Answer 1

Answer:

f(x) = g(x - 3)(x - 5) for some g

f(x) = g(x^2 - 8x + 15)

Substitute (4, -1) for (x, f(x)) and solve for g.

-4 = g(4^2 - 8(4) + 15)

-4 = g(-1)

g = 4

f(x) = 4x^2 - 32x + 60

Answers

Answer:

2

Step-by-step explanation:

First, translate the expression '' x is equal to 6 less than the length''
w= L - 6
Then, draw a picture and replace the width with L - 6
Then come up with the perimeter of the rectangle.

A 4L + 12
B 4L - 12
C 2(6 - L ) + 2L
D 2( L- 6) + 2L
E 12 + 2L + 2L

Answers

Answer:

B 4L- 12

D 2(L -6) + 2L

Step-by-step explanation:

Perimeter is 2w + 2l, width is 6 less that length, so substitute it for w:

2w + 2l =

2(L - 6) + 2l =

2l - 12 + 2l =

2l + 2l - 12 =

4L - 12
