Question 928705: Determine the quadratic function f with a vertex of (2,-7) and the other given point is (3,0)
Answer by ewatrrr(24785) (Show Source): You can put this solution on YOUR website!
f(x) = a(x-2)^2 - 7
0 = a(3-2)^2 - 7
7 = a
f(x) = 7(x-2)^2 - 7
.......
completing the Square
P(x)=-x^2+7x-13
P(x) = -(x-7/2)^2 + 49/4 - 52/4
P(x) = -(x-7/2)^2 - 3/4
