    1. The problem statement, all variables and given/known data
    Sketch the region enclosed by the given curves. Decide
    whether to integrate with respect to x or y. Draw a typical approximating
    rectangle and label its height and width. Then find the
    area of the region.
    2. Relevant equations



    3. The attempt at a solution



    My result gave me an answer "-20". The area cannot be negative, please check my answer for a mistake?

    If you want to find the area between two curves f(x) and g(x), how do you know whether to integrate f(x)-g(x) or g(x)-f(x)? Use your graph.
