In order to determine if the improper integral a dx converges, we might compare it to the power function1 7 1 0 First, what is the relationship between these function when x 2 7 8 5 is greater their 6 less them 2 5 equal to what do we know about 1 dn ? we know that it 2 diveyes converges what do these facts tell us about whether the integral ( 25 do conveyes or diverges ? 6 the integral diverges no information the intepod converges
