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)=9−x2;
[−1,6]

You can put this solution on YOUR website!
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.
