Consequently, to determine the intervals where a function \(f\) is concave up and concave down, we look for those values of \(x\) where \(f''(x)=0\) or \(f''(x)\) is undefined. When we have determined these points, we divide the domain of \(f\) into smaller intervals and determine the sign of \(f''\) over each of these smaller intervals. Our definition of concave up and concave down is given in terms of when the first derivative is increasing or decreasing. We can apply the results of the previous section to find intervals on which a graph is concave up or down. That is, we recognize that \(\fp\) is increasing when \(\fpp>0\text{,}\) etc. Theorem 3.4.4 Test for Concavitycurves upward, it is said to be concave up. If the function curves downward, then it is said to be concave down. The behavior of the function corresponding to the second derivative can be summarized as follows 1.

We say this function f f is concave up. Figure 4.34(b) shows a function f f that curves downward. As x x increases, the slope of the tangent line decreases. Since the derivative decreases as x x increases, f ′ f ′ is a decreasing function. We say this function f f is concave down. Inflection Points. An Inflection Point is where a curve changes from Concave upward to Concave downward (or vice versa) So what is concave upward / downward ?
