# Thread: Finding the area under a curve

1. ## Finding the area under a curve

Some of my homework questions say 'find the area under the curve (insert function here) and the x axis.' I know how to integrate and all, but what do I do when they don't give you boundaries?

2. Find the x-intercepts of the function, which give bounded regions between the x-axis and the curve. i.e solve f(x) = 0 and use these x-values for the limits when you integrate.

3. duh. lol thanks i completely forgot about the x intercepts!
