Question

PLEASE HELP!! What is the equation of the following graph in vertex form?

Answer 1

y = (x - 4)² - 4

Explanation:

The vertex form of an equation of the parabola:

f(x) = a(x - h)² + k

the vertex is (4, -4) ⇒ h = 4, k = -4

so:

f(x) = a(x - 4)² + (-4)

f(x) = a(x - 4)² - 4

So the right answer is the first one.
