Question

Given the function below, what is the value of g(4)? g(x) = 3x² - 3x -9

Answer 1

We have the function:

`g(x)=3x^2-3x-9`

To find g(4) we need to plug four instead of x in the function, then:

`\begin{gathered} g(4)=3(4)^2-3(4)-9 \\ =3(16)-12-9 \\ =48-12-9 \\ =27 \end{gathered}`

Therefore g(4)=27
