$f(2)=2 \text{ and } f(-1)=-4$

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 $ 2 .$ Hence, $ f(2)=2 .$ b) Using the graph, when $x=-1,$ the value of $y$ is $ -4 .$ Hence, $ f(-1)=-4 .$ Hence, $ f(2)=2 \text{ and } f(-1)=-4 .$
