Answer
a) $f(-2)=3$
b) $f(0)=3$
c) $f(1)=3$
d) $f(4)=3$
Work Step by Step
a) When $x=-2,$ the corresponding $y-$value in the given graph is $
3
.$ Hence,
\begin{array}{l}\require{cancel}
f(-2)=3
.\end{array}
b) When $x=0,$ the corresponding $y-$value in the given graph is $
3
.$ Hence,
\begin{array}{l}\require{cancel}
f(0)=3
.\end{array}
c) When $x=1,$ the corresponding $y-$value in the given graph is $
3
.$ Hence,
\begin{array}{l}\require{cancel}
f(1)=3
.\end{array}
d) When $x=4,$ the corresponding $y-$value in the given graph is $
3
.$ Hence,
\begin{array}{l}\require{cancel}
f(4)=3
.\end{array}
