Compute the value of the improper integral. (If the integral diverges to oo, type oo; if the integral diverges to - oo, type -oo; and if the integral diverges for some other reason, type DNE.) OO dx N (72 - 12)? Use your answer to help determine whether the series converges or diverges. Enter C if 2 (7n - 12)7 the series is convergent, D if the series is divergent, or ? if the Integral Test does not apply
