Question

If f is a function whose domain includes all real numbers, the improper integral ∫∞−∞f(x)dx is defined to equal ∫0−∞f(x)dx∫∞0 f(x)dx provided both of those improper integrals converge. with that definition in mind, the improper integral ∫∞−∞x 31+x 4 dx will:

Answer 1

Polynomials are unbounded, so the integral will diverge.
