Determine the vertex of the function f (x) = 2 (x - 5) 2 + 8.

A. (8-5)

B. (8,5)

C. (-5, 8)

D. (5.8)

Solve for x, which can be done by moving x to the other side.

2 (x-5) ^2+8

So, x = 5

The y value is the number at the end and we can see that it is positive 8.

y = 8

Write it out as a coordinate pair and you would get (5,8) or answer choice D
