How to Find Critical Values/Critical Numbers (Calculus 1) | Math with Professor V

Four classic examples of how to find critical values/critical numbers for functions. Step-by-step explanation of how to take derivatives, then simplify and "clean up" f'(x) so you can easily solve for the critical values. Not intended as a conceptual lecture, but simply to help you with the mechanical and computational aspect of finding critical values.
