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 $LaTeX: \displaystyle (5, 8)$ local min $LaTeX: \displaystyle (-8, -7)$ . The function is decreasing on $LaTeX: \displaystyle (-\infty, -8) \cup (5, \infty)$ and increasing on $LaTeX: \displaystyle (-8, 5)$ .
