# Math (Reflection across y=x line)

Here's a question that I am having trouble with:

What is the resulting equation when y=x^3+2x^2 is reflected across the y=x line?

I know that I need to switch the y with the x's in the equation, so is the answer they're looking for simply x=y^3+2y^2 or do I need to simplify further to get y isolated on one side of the equation?
