For questions $21-23,$ use the following graph of $y=f(t)$ :

Let $F(x)={\displaystyle \underset{2}{\overset{x}{}}}f(t)dt.$

$21.F(-2)=$

$($A$.)-4$

$($B$.)0$

$($C$.)4$

$($D$.)-2$

$($E$.)1\mathrm{.}5$

$22.F^{\text{'}}(-2)=$

$($A$.)1$

$($B$.)2$

$($C$.)-3$

$($D$.)0$

$($E$.)-2$

$23.F(x)$ has a local minimum at

$($A$.)x=2$

$($B$.)x=-1$ and $x=4$

$($C$.)x=1$

$($D$.)x=-1$

$($E$.)x=4$
