Help!!!!!!!!!!!!!!!!!!!!!!!
Nataly [62]
Hello.

Firstly, let's isolate x on the equation:

\mathsf{f(x) = 3x + 3} \\ \\ \mathsf{y = 3x + 3} \\ \\ \mathsf{-3x = -y + 3} \\ \\ \mathsf{x = \dfrac{-y + 3}{3}}

Now, we can replace 'x' for 'y' and vice-versa:

\mathsf{f^{-1}(x) = \frac{-x + 3}{3}`}

Hope I helped.
