    area can be found through integration. You don't necessarily need to sketch unless the question asks you to do so specifically.

    Is the question to find the area between those two functions?

    g(x) is a cubic|dw:1356373761763:dw| the parabola is your upper function

    setting the equations equal to each other will allow you to find your bounds...if your not sure of the upper function, guess. if wrong you'll get a negative answer and you just have to change the sign
