WebIncreasing and Decreasing Functions. Let y = f (x) be a differentiable function (whose derivative exists at all points in the domain) in an interval x = (a,b). If for any two points x 1 and x 2 in the interval x such that x 1 < x 2, there holds an inequality f (x 1 ) ≤ f (x 2 ); then the function f (x) is called increasing in this interval.

WebFeb 15, 2016 · The usual way of proving that a function is non-decreasing is to analyze the sign of its first derivative: roughly, given a function f, it will be non-decreasing if f ′ ( x) ≥ 0. Since your function is continuous and has no singularity, you just need to compute F ′ and observe that it can never be negative.
