Function concave up and down calculator.

For functions de ned on non-open sets, continuity can fail at the boundary. In particular, if the domain is a closed interval in R, then concave functions can jump down at end points and convex functions can jump up. Example 1.

Graphically representation: From the graph, we see that the graph shows two different trends before and after the ...Maximum preserves convexity and minimum preserves concavity. So the maximum of two concave functions may be neither concave nor convex. It may become double peaked. For example, f(x) = max[−|x + 1|, −|x − 1|] f ( x) = max [ − | x + 1 |, − | x − 1 |] has an "M"-shaped graph. The minimum of two concave functions is always concave.We say this function \(f\) is concave up. Figure \(\PageIndex{6b}\) shows a function \(f\) that curves downward. As \(x\) increases, the slope of the tangent line decreases. Since the derivative decreases as \(x\) increases, \(f^{\prime}\) is a decreasing function.
