Question

Rewrite the function f(x)=4(x-2)²-8 in the form f(x)=ax²+bx+c.

Answer 1

`f(x) = 4x^2 -16x + 16`

Explanation:

f(x)=4(x-2)² Simplify.

f(x) = 4x^2 - 16x + 16

Form f(x)=ax²+bx+c.

f(x) = 4x^2 - 16x + 16

Answer 2

4
`x^(2)`-16x+8

Explanation:

4(x - 2)(x - 2) - 8 = 4(
`x^(2)` - 4x + 4) - 8 = 4
`x^(2)` - 16x + 16 - 8 = 4
`x^(2)` - 16x + 8.
