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