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}
