g(3)=22


g(-(5)/(9))=-10

Step-by-step explanation

Evaluating a function means to substitute a variable with its given number or expression and calculate


g(x)=9x-5

Step 1

when x= 3, so

replace the x place with 3


\begin{gathered} g(x)=9x-5 \\ g(3)=9(3)-5 \\ g(3)=27-5 \\ g(3)=22 \end{gathered}

hence


g(3)=22

Step 2

when


x=-(5)/(9)

replace


\begin{gathered} g(x)=9x-5 \\ g(-(5)/(9))=9(-(5)/(9))-5 \\ g(-(5)/(9))=-5-5 \\ g(-(5)/(9))=-10 \end{gathered}

therefore


g(-(5)/(9))=-10

I hope this helps you
