Question

Write each function in standard form .
F(x)= -2(x-9)2 +15

hintHint:

The standard quadratic form is ax2+bx+c=y, the vertex form of a quadratic equation is y=a(x−h)2+k.

The correct answer is: f(x) = -2x2 + 36x - 147.


    We have given the function in Vertex form , we have to convert it into standard form.
    F(x)= -2(x-9)2 +15
    On further solving this function we will get
    F(x) = -2 ( x2 - 18x + 81 ) + 15
    = -2x2 + 36x - 162 + 15
    = -2x2 + 36x - 147
    Therefore, the standard form of given function is f(x) = -2x2 + 36x - 147.
