In addition to asking whether a function is increasing or decreasing, it is also natural to inquire how a function is increasing or decreasing. To begin, there are three basic behaviors that an increasing function can demonstrate on an interval, as pictured in Figure 1.29: the function can increase more and more rapidly, increase at the same rate, or increase in a way that is ... For example, the function x2 x 2 takes the reals (domain) to the non-negative reals (range). The sine function takes the reals (domain) to the closed interval [−1,1] [ − 1, 1] (range). (Both of these functions can be extended so that their domains are the complex numbers, and the ranges change as well.) Wolfram|Alpha brings expert-level ... Locations where the function's value changes from decreasing to increasing (a trough) are called relative minimums. In some cases, a relative extremum point can also be an absolute extremum point. For example, f(x) = x 2 changes from decreasing to increasing at x = 0 which is a relative minimum.

A function is concave down when its gradient decreases as its values increase. I like to think of a parabola with the ends pointing downwards (one that's 'upside down'). You might have written descriptions of concave down curves in Physics classes. They're the ones that are 'increasing at a decreasing rate' or 'decreasing at an increasing rate'.Free math problem solver answers your algebra, geometry, trigonometry, calculus, and statistics homework questions with step-by-step explanations, just like a math tutor.
