#### Answer

$f(2)=-3 \text{ and } f(-1)=2$

#### Work Step by Step

$\bf{\text{Solution Outline:}}$ To find $f(2)$ and $f(1),$ use the given graph to find the value of $y$ when $x=2$ and when $x=-1.$ $\bf{\text{Solution Details:}}$ a) Using the graph, when $x=2,$ the value of $y$ is $-3 .$ Hence, $f(2)=-3 .$ b) Using the graph, when $x=-1,$ the value of $y$ is $2 .$ Hence, $f(-1)=2 .$ Hence, $f(2)=-3 \text{ and } f(-1)=2 .$
