Set the two functions equal to each other and solve for the variable to find that particular intersection point. For this one, it might be easier to do with a graphing calculator and using the "Intersect" function.

if you set them equal and try to solve you bury the variable in the second function behing more functions making even more difficult. If I use the graphing calculator method will it give me an accurate enough interval for an integral?

Yes, using a graphing calculator to find the intersection point, and keeping about 3 or 4 decimal places, is usually enough to carry out definite integrals. That's actually how they'd expect you do to a problem like this on a real calculus exam.
