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

vertex = (4, - 8)

Step-by-step 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
