WebYou can see the graph of f (x) = x 2 below. The graph of f (x) = x 2 is convex (concave up) at all values of x because the second derivative is positive everywhere. Example 2: Finding the Concavity of f (x) = x 3 Consider the function f (x) = x 3. The first derivative is f’ (x) = 3x 2, by the power rule.

Recall that f is differentiable at x if lim h → 0 f ( x + h) − f ( x) h exists. And so we see that f is differentiable at all x ∈ R with derivative f ′ ( x) = − 5. inc007
