The Derivative as a function

[somber pollen]

Hello, I am having trouble finding f'(x). I'm not sure what to do with the f'(x)=0 because when I plug it in, I get 0

[glacial zealot]

Wait, I'm confused. If you're having trouble finding f'(x), how would you do anything with f'(x) = 0?

...right, and when is that 0?

.

solving for f'(x) = 0 for x

I see, thanks! @quaint estuary

I thought I had to get an actual number for that part, but I just need to put f'(x)= (x^2+22x)/(x^2+22x+22) for the first part, correct? @quaint estuary

[glacial zealot]

...yes, that's what the problem explicitly states.

[quaint estuary]

yes
