8 Consider the series S = n=15 (n+4)5/2 To test S for convergence by a direct application of the integral test, one would calculate S dx = (Fill in the corresponding integrand and the value of the improper integral. Enter a number if possible, or inf for co, -inf for-co, or div if no earlier in According to the Integral Test, the series S = A. converges n n=15 (n+4)5/2 B. diverges C. not enough information to determine
