    Okay so I am trying to find the area of a region but I having a problem with a simple intermediate step!! I have...
    f(y) = y^2
    g(y) = y + 2
    I need to find the y-coordinates of where the 2 lines intersect. Can someone please help me???

    Set them equal to each other and solve for y.

    At the point of intersection, y2= y+ 2. Solve y2- y- 2= 0.
