Find the derivative, set equal to zero and solve for x
find C(x)

at x = 0
I think you have a typo probably.
As shown this function starts at zero and keeps getting bigger forever.
Did you leave a negative sign out?

No, there's no typo. That's what I can't figure this out. I put zero and it's wrong.
