Use the Integral Test to determine whether the series is convergent or divergent. 4 n= 1 n9 In order to apply the Integral Test for the function f(x) on the interval [a, co), which of the following must be true? (Select all that apply.) Of is continuous. Of is differentiable. Of is positive. Of is negative. Of is increasing. Of is decreasing. For E 4 no . since f ( ac ) = 4 79 satisfies the conditions on [1, co), we consider the following. n=1 (If the quantity diverges, leave this blank.) 4 dx = lim b -+ 0o Therefore, 4 I v Select an answer n = 1 n9 convergent divergent
