The Comparison Test is also useful to show that an improper integral such as int g(x)dx diverges, again by comparing it against another divergent integral which is easier to calculate. If 0≤f(x), What can be concluded about the convergence of the integral int f(x)dx?
1) The integral int f(x)dx converges
2) The integral int f(x)dx diverges
3) The convergence of the integral int f(x)dx cannot be determined
4) The integral int f(x)dx is equal to zero
