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. illumagear halo light priceWebMay 22, 2015 · Since x 2 2 ≥ 2 for x ≥ 2 and x ≤ − 2, your function will increase on those intervals. So, you need to only consider − 2 ≤ x ≤ 2. Both cos ( x) and x 2 2 are even functions. This allows us to only consider − 2 ≤ x ≤ 0. On this interval cos ( x) is an increasing function. Thus cos ( x) − 1 is also increasing. In addition x 2 2 is increasing. illuma health singaporeWebWhen there are no values in the domain of a function such that f ′ ( x) = 0, then it is always increasing, if f ′ ( x) > 0, or it is always decreasing, if f ′ ( x) < 0, since there is no point at which a "transition point" (where f ′ ( x) = 0) exists.
