Question 1143551: Determine without graphing, whether the given Quadratic Function has a maximum value or a minimum value and then find that value.
I know bc it is negative -5x^2 it opens downward, so it is a maximum value. I thinking that part is right???
I'm confused on how to find the value
I could really use some help.
I put in a & b into x= -b/ 2a
But I'm just not sure if that's what I'm supposed to use to get the answer
Duh & Double duh

=================
y = -5x^2 does have a maximum.

I could really use some help.
I put in a & b into x= -b/ 2a
The max is at x = -b/2a
b = 0
---> max at x = 0
----> the point (0,0) is the max.
