Note: We often state that "\(f\) is concave up" instead of "the graph of \(f\) is concave up" for simplicity. A graph is increasing or decreasing given the following: Given any x 1 or x 2 on an interval such that x 1 < x 2, if f (x 1) < f (x 2 ), then f (x) is increasing over the interval. WebA confidence interval is a statistical measure used to indicate the range of estimates within which an unknown statistical parameter is likely to fall. Break up domain of f into open intervals between values found in Step 1. Interval 3, \((0,1)\): Any number \(c\) in this interval will be positive and "small." We conclude \(f\) is concave down on \((-\infty,-1)\). Show Point of Inflection. If f"(x) > 0 for all x on an interval, f'(x) is increasing, and f(x) is concave up over the interval. If knowing where a graph is concave up/down is important, it makes sense that the places where the graph changes from one to the other is also important. The function has an inflection point (usually) at any x-value where the signs switch from positive to negative or vice versa.
