The second derivative itself doesn't prove concavity. Like the first derivative, the second derivative proves the first derivative's increase/decrease (if the second derivative is positive, the first derivative is increasing and vice versa). The second derivative test is used to find potential points of change in concavity (inflection points).Similarly, a function is decreasing on an interval if the function values decrease as the input values increase over that interval. The average rate of change of an increasing function is positive, and the average rate of change of a decreasing function is negative. Figure 3 shows examples of increasing and decreasing intervals on a function.A closed interval notation is a way of representing a set of numbers that includes all the numbers in the interval between two given numbers. In this notation, the numbers at the endpoints of the interval are included in the set. The notation for a closed interval is typically of the form [a,b], where a and b are the endpoints of the interval. Let’s take a look at an example of that. Example 1 For the following function identify the intervals where the function is increasing and decreasing and the intervals where the function is concave up and concave down. Use this information to sketch the graph. h(x) = 3x5−5x3+3 h ( x) = 3 x 5 − 5 x 3 + 3.
