We want to know about a function $h(x),$ but we are glven its first derivative $h^{\text{'}}(x).$ That is$,$ suppose that the derivative $h^{\text{'}}(x)=(x1)(x-2).$ On what interval $($s$)$ is the function $h(x)$ increasing, and on what intervally is $h(x)$ decreasing? Where does $h(x)$ have a local

$($a$)h(x)$ is increasing on the interval$/$s$)$

$($b$)h(x)$ is decreasing on the interval$($s$)$

$($c$)h(x)$ has a local maximum at $$

$($d$)h(x)$ has a local minimum al $$
