For g(x)= 9x-5, find g(3) and g( -5/9)(Simplify Answer)
Alborosie

g(3)=22

g(-\frac{5}{9})=-10

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=-\frac{5}{9}

replace

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

therefore

g(-\frac{5}{9})=-10

I hope this helps you
