determine the vertex of the function f(x) = 2(x - 5)2 + 8.
a.(8-5)
b.(8,5)
, 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

Ibelieve the answer is b. y=0 would make the line horizontal across the x.
