    Question calculus area question

    I have an idea on this one by looking at the graph, but want to be sure. If f(x)=x^2 -1 and g(x)= 1-x^2, what is the area bound by the graphs of f and g? I came up with 2 units... Correct or no?

    Area = \int g(x) - f(x) dx

    *or

    Area = \int top function - bottom function dx

    No, that is not correct. Please show exactly what you did.
