I need to find the inverse of the function [tex]f\left( x \right) = x^2 + 6x\[/tex] with the domain of [tex]x \ge - 3[/tex] and [tex]x \le - 3[/tex].

What i have done so far:

[tex]

\begin{array}{c}

f\left( x \right) = x^2 + 6x \\

x = y^2 + 6x \\

\end{array}

[/tex]

and then from here I need to put the 2nd function in terms of y, however I do not know how to because of the function having the variable y twice. I am not asking for the answer of the problem, only suggestions on which way to approach the situation.

Many thanks
