Answer

a) $f(-2)=5$ b) $f(0)=0$ c) $f(1)=2$ d) $f(4)=4$

Work Step by Step

a) When $x=-2,$ the corresponding $y-$value in the given graph is $ 5 .$ Hence, \begin{array}{l}\require{cancel} f(-2)=5 .\end{array} b) When $x=0,$ the corresponding $y-$value in the given graph is $ 0 .$ Hence, \begin{array}{l}\require{cancel} f(0)=0 .\end{array} c) When $x=1,$ the corresponding $y-$value in the given graph is $ 2 .$ Hence, \begin{array}{l}\require{cancel} f(1)=2 .\end{array} d) When $x=4,$ the corresponding $y-$value in the given graph is $ 4 .$ Hence, \begin{array}{l}\require{cancel} f(4)=4 .\end{array}
