The domain of the function $h$ graphed below is all real numbers, and all of its extreme values occur when $-3<x<3$. Use the graph to answer the following questions.

True or false: every relative maximum and minimum of $h$ occurs at a point where $h'(c)$ is either zero or does not exist. ? True False

True or false: at every point where $h'(c)$ is zero or does not exist, $h$ has a relative maximum or minimum. ? True False
