Compute the value of the improper integral. (If the integral diverges to co, type oo; if the integral diverges to - oo, type -oo; and if the integral diverges for some other reason, type DNE.) dx N 6 + 8 1 Use your answer to help determine whether the series M converges or diverges. Enter C if the n = 2 6n + 8 series is convergent, D if the series is divergent, or ? if the Integral Test does not apply
