WebOne way to approach this question is to consider the minimum of x − log a x on the interval ( 0, ∞). For this we can compute the derivative, which is 1 − 1 / ( log e a) ⋅ x. Thus the derivative is zero at a single point, namely x = 1 / log e a, and is negative to the left of that point and positive to the right. WebApr 9, 2024 · If f (x) is a Monotonically Increasing Function over a given interval, then −f (x) is said to be a Monotonically Decreasing Function over that same interval, and vice-versa.
