Thread: Simple Critical Point Problem

Hello all,

Here is a pretty simple equation that I need to find the critical points for. I know how to find the critical points for an equation, but I'm not able to figure this one out.



=>
0 =

I got -21 and 0 for my critical values. Are there any more?

I think you're trying to find when the first derivative is zero. At x=0 and x=-21 the derivative blows up (denominator is zero). If I got the derivative right, I think x=-7 is what you're looking for.
