Question

A quadratic function f(x) is hidden from view. You must find the maximum value of the function f(x). Choose the form of the quadratic function f(x) that you would like to see in order to answer the question most efficiently.

Answer 1

Vertex Form is what you want if you want to be able to see the vertex (max or min) from the function.

f(x) = a(x-h)^2 + k

In this form, (h,k) is the min or max (depending if the parabola opens up or down).
