WebMar 24, 2016 · Consider f (x) = √x +3 6x + 3. Differentiate to get: f '(x) = −6x 2(6x + 3)2√x +3 For x ≥ 1, we see that f '(x) < 0, so f is decreasing for x ≥ 1. Therefore, the sequence is decreasing. For the fourth sequence, we get f '(x) = − sinx +ln3cosx 3x. It may take some work to convince ourselves that the sign of f ' must change.
