quadratic word problem

Question

Given two functions f(x) = - 5x2 – 7x + 4 and q(x)= (2+x)(3-x), explain which function has a smaller maximum value.

Answer 1

Hello,

I would start by using the quadratic formula in order to determine the maximum value of each of the functions. Once you know the two maximum values, you will be able to determine which is smaller.
