Use comparison test to see if the integral is convergent or divergent.

Homework Equations



integral [1,∞] (2+e^(-x))/x



The Attempt at a Solution



My books says that (1+e^(-x))/x is divergent and since my integral is bigger it is divergent also.
TRUE OR FALSE? Thanks for the help

Compare your integral with ##\int_1^\infty \frac 2 x~dx##.
