SOLUTION

Step1: write out the expression


f(x)=22x+12

Step2

Evaluate f(5) by substituting x=5 into f(x)


\begin{gathered} f(5)\text{ implies that x=5} \\ \text{substitute x=5 into f(x)} \\ f(x)=22x+12 \\ f(5)=22(5)+12 \\ f(5)=110+12 \\ f(5)=122 \end{gathered}

Therefore

The value of f(5) is 122
