Question

Rewrite f(x) = –2(x − 3)2 + 2 from vertex form to standard form.

f(x) = –2x2 − 18
f(x) = –2x2 + 12x + 20
f(x) = –2x2 + 12x − 16
f(x) = 4x2 − 24x + 38

Answer 1

Answer: C. f(x) = –2x2 + 12x − 16

Rewrite f(x) = –2(x − 3)2 + 2 from vertex form to standard form.

A. f(x) = –2x2 − 18

B. f(x) = –2x2 + 12x + 20

C. f(x) = –2x2 + 12x − 16

D. f(x) = 4x2 − 24x + 38

Explanation:

I just did the assignment and the correct answer is f(x) = –2x2 + 12x − 16! Hope this helps.

Good Luck!!

Answer 2

`f(x)=-2(x-3)^2+2\\f(x)=-2(x-3)(x-3)+2\\f(x)=-2(x^2-3x-3x+9)+2\\f(x)=-2(x^2-6x+9)+2\\f(x)=-2x^2+12x-18+2\\f(x)=-2x^2+12x-16`

-2x^2+12x-16
