I have a question about how to obtain an equation of an inverse function.
The equation is $y=x^2+2x+3$ and I changed $x$ and $y$ to get $x=y^2+2y+3$ and it is only a matter of rearranging to have $y$ on the left side but I am finding it difficult to do so.
I got $y(y+2)=x-3$ but since there are 2 of the $y$ on one side I am unsure how to make $y$ the subject.
I have googled for solutions and they had $y$ on both sides, how would I have $y$ as a subject?
