# Function symmetric  with respect to the bisector of first and third quadrant

What's the symmetric function in respect to the bisector of first and third quadrant of $y= \frac{x^2}{1-x}$ . Find the area that the two functions describe in the first quadrant

• The question is a little unclear. Do you want to find the equation of the function obtained by reflecting the graph of the given function with respect to y=x?

• yes
