Question

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

Answer 1

`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`
