Question

Write the equation in vertex form using the following information: vertex (4, -6) and a=1.

Answer 1

y = (x - 4)² - 6

Explanation:

An equation of a quadratic function in a vertex form is y=a(x-h)²+k, where vertex is (h, k)

vertex (4, -6) means h = 4 and k = - 6

So:

y = 1(x - 4)² + (-6)

y = (x - 4)² - 6
