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.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.The concavity of the function changes from concave up to concave down at 𝑥 = − 2 3. This is a point of inflection but not a critical point.
