Use the limit comparison test to determine whether >an => 8n3 - 8n2 +19 n=19 n=19 6 + 4n4 converges or diverges. (a) Choose a series on with terms of the form on = - and apply the limit comparison test. Write your answer as a fully simplified fraction. For n 2 19, n=19 lim an lim (b) Evaluate the limit in the previous part. Enter co as infinity and -co as -infinity. If the limit does not exist, enter DNE. lim an 1 too on (c) By the limit comparison test, does the series converge, diverge, or is the test inconclusive? Choose
