Question

Let f(x)=12x-3 and g(x)=4x+2. Find f(g(x))

Answer 1

`{ \qquad\qquad\huge\underline{{\sf Answer}}}`

here we go ~

`\qquad \sf  \dashrightarrow \: f(x) = 12x - 3`

and

`\qquad \sf  \dashrightarrow \: g(x) = 4x + 2`

now, let's find f(g(x)) :

`\qquad \sf  \dashrightarrow \: f(g(x)) = 12(4x + 2) + 2`

`\qquad \sf  \dashrightarrow \: 48x + 24 + 2`

`\qquad \sf  \dashrightarrow \: 48x + 26`
