Assume that $f$ is continuous on $-4,4$ and differentiable on $(-4,4).$ the table gives some values of $f^{\text{'}}(x).$

$\backslash$table$[[x,-4,-3,-2,-1,0,1,2,3,4],[f^{\text{'}}(x),-55,-22,3,21,30,32,20,0,-40]]$

Estimate where $f$ is increasing, decreasing, and has local extrema.

$7.$ Increasing:

Decreasing:

Local min:$x$~~ $$

Local max: $x$~~ $$
