Question 923777: I need help!
Use the definite integral to find the area between the x-axis and f(x) over the indicated interval. Check first to see if the graph crosses the x-axis in the given interval.

f(x) crosses the x-axis at x = 3. f is positive on [-1, 3) and negative on (3, 6].

And you can simplify the rest.
