a) $f(2)=5$ b) $f(-1)=11$
a) When $x=2,$ the corresponding $y-$value in the given set of ordered pairs is $5 .$ Hence, \begin{array}{l}\require{cancel} f(2)=5 .\end{array} b) When $x=-1,$ the corresponding $y-$value in the given set of ordered pairs is $11 .$ Hence, \begin{array}{l}\require{cancel} f(-1)=11 .\end{array}
