Consider the series. Σ n=1 an = Let f(x) = In (x) 4x² (Express numbers in exact form. Use symbolic notation and fractions where needed.) f'(x) = Evaluate n=1 -∞ In (x) 4x² [₂ In (n) 4n² • hº (Express numbers in exact form. Use symbolic notation and fractions where needed.) Find f'(x). In (x) 4x² dx = dx. Identify the true statement(s) about the series and the integral. f'(x) < 0 for all x ≥ 2, so f is eventually decreasing. The integral ₂ f(x) dx is finite, so the series converges by the Integral Test. f(x) > 0 and is continuous for all x ≥ 2. The Integral Test does not apply since f(x) is not continous on (1, 00). The Integral Test does not apply since the function is only increasing when x ≥ 1. The integral ₂ f(x) dx is infinite, so the series diverges by the Integral Test.
