Question

What is the vertex for the following quadratic? f(x)=2(x - 4)^2 -8

Answer 1

vertex = (4, - 8 )

Explanation:

The equation of a quadratic in vertex form is

f(x) = a(x - h)² + k

where (h, k) are the coordinates of the vertex and a is a multiplier

f(x) = (x - 4)² - 8 ← is in vertex form

with (h, k ) = (4, - 8 ) ← coordinates of vertex
