Which function in vertex form is equivalent to f(x) = x2 + 8 – 16x? a. f(x) = (x – 8)2 – 56 b. f(x) = (x – 4)2 + 0 c. f(x) = (x + 8)2 – 72 d. f(x) = (x + 4)2 – 32

The correct option is A.

Explanation:

The given function is,

Rewrite the above function.

To make the perfect square we add and subtract the square of , where b is coefficient of x and a is the coefficient of .

Since a=1 and b = -16, So we will add and subtract he square of -8.

Using

Therefore, the correct option is A.
