\qquad\qquad\huge\underline{\boxed{\sf Answer☂}}

To find g(4), we have to substitute the variable x with 4 on the expression g(x) ~


\qquad \sf  \dashrightarrow \: g(x) = 3x - 7


\qquad \sf  \dashrightarrow \: g(4) = 3(4)- 7


\qquad \sf  \dashrightarrow \: g(4) = 12- 7


\qquad \sf  \dashrightarrow \: g(4) =5
