HELP! Find the area between the curves. Simplify your answer integer or improper fraction. x=-2 x=3 y=10x y=x^2-11

    Can we do this? and add the integrals? |dw:1436810481143:dw|

    There is some ambiguity to this question. Here is a graph

    They may mean add the two "subareas" or possibly, treat the left subarea as negative.

    yeah I don't know. I lose all my confidence when it comes to setting up the area and volume integrals

    Yeah, I've been stuck on this for a while now. A graph was not given either.

    I was thinking literally the area between the curves, so switch the upper and lower curve where they intersect. not sure though

    we've to find 5 coordinate points. then use integral.

    \(\int_{-2}^{3} \ x^2 - 10 x - 11 \ dx\) there cannot be more to it than that, surely?

    @IrishBoy123 I thought you had to switch the order of the curves if they intersect within the limits.

    if we are interested in finding the positive area between the curves (i.e. the size of the area we would paint), then we would break the integral into two regions: \[ \int_{-2}^{-1} x^2-11 - 10x \ dx + \int_{-1}^3 10x - x^2 +11 \ dx \]
