Suppose f and g are continous functions with f(x) g(x) 0 for x a then
(A) If integral a to infinity f(x) dx is convergent, then integral a to infinity g(x) dx is convergent
(B) If integral a to infinity f(x) dx is divergent, then integral a to infinity g(x) dx is divergent
(C) If integral a to infinity f(x) dx is convergent, then integral a to infinity g(x) dx is divergent
(D) If integral a to infinity f(x) dx is divergent, then integral a to infinity g(x) dx is convergent
i have no idea on this one..
