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

Answers

f(x) = x² + 8 - 16x

I'll rearrange it using y and x.

y = x² - 16x + 8
y - 8 = x² - 16x
y - 8 + 64 = x² - 16x + 64
y + 56 = (x-8)²
y = (x-8)² - 56

(x - 8)(x - 8) = x(x-8) - 8(x-8) = x² - 8x -8x + 64 = x² - 16x + 64

Choice A.) f(x) = (x-8)² - 56

By completing the square, the function in vertexform f(x) = (x - 8)² - 56 is equivalent to the function in standardform f(x) = x² + 8 - 16 · x. (Correct choice: A)

How to determine the vertex of the quadratic function by algebraic means

In this question we must transform a quadraticfunction in standardform into vertexform. An analytical approach is completing the square, which consists in transforming part of the polynomial into a perfect squaretrinomial. Now we proceed to present the procedure:

1) x² + 8 - 16 · x Given

2) x² - 16 · x + 8 Commutative property

3) x² - 16 · x + 64 - 56 Modulative property/Existence of additive inverse/Definition of addition

4) (x - 8)² - 56 Associative property/Perfect square trinomial/Result

By completing the square, the function in vertexform f(x) = (x - 8)² - 56 is equivalent to the function in standardform f(x) = x² + 8 - 16 · x. (Correct choice: A)
