1. The problem statement, all variables and given/known data I need to sketch these curves and find where they intersect: x+y-y^3 = 0 x-y+y^2=0 2. Relevant equations 3. The attempt at a solution I have no idea what these are supposed to look like.. other than that x = -y^2+y is a sort of parabola that opens to the right. Any tips as to how to understand functions in these forms?
