Question 209941: Without graphing, find the vertex. The answer is either A,B,C,or D.
f(x) = -15/2 (x - 15)2 + 2
I came up with Vertex: (-450x,0, but this is the wrong answer.
A)(0, 2)
B)(15, -15)
C)(15, 2)
D)(2, 0)

You can put this solution on YOUR website! Without graphing, find the vertex. The answer is either A,B,C,or D.
f(x) = (-15/2) (x - 15)^2 + 2
The form is y = a(x-h)^2+k
where the vertex is at (h,k)
Your vertex is (15,2)
