Can anyone explain how to do these two problems? I don't understand them at all:
Thanks
In other words, $\displaystyle f'(x) = 0$. I assume you can find the derivative of $\displaystyle f(x)$. Then, find values of $\displaystyle a$, $\displaystyle b$, $\displaystyle c$ for which the equation $\displaystyle f'(x) = 0$ has exactly two, exactly one, or no solutions.
