Critical numbers help
We just started doing local and absolute maximum and minimum numbers and on the practice version of our homework one of the problems says:
Find the value C so that F(x)=2x^(3)-3x^(2)+CX+2 has only one critical number.
How do i solve a problem like this?
When you take the derivative you get a quadratic function.

The discriminant is the part of the quadratic equation.
This should get you started.
Solved it, and the actual homework problem. Thanks alot
