Use the graph to find any relative maxima or minima of the function. Find the intervals of which the function is increasing or decreasing.

The local max $LaTeX: \displaystyle (8, 9)$ local min $LaTeX: \displaystyle (-2, -8)$ . The function is decreasing on $LaTeX: \displaystyle (-\infty, -2) \cup (8, \infty)$ and increasing on $LaTeX: \displaystyle (-2, 8)$ .
