$f(2)=3 \text{ and } f(-1)=-1$
$\bf{\text{Solution Outline:}}$ 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 $-1 .$ Hence, $f(-1)=-1 .$ Hence, $f(2)=3 \text{ and } f(-1)=-1 .$
