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