Concave interval calculator

f (x) = x³ is increasing on (-∞,∞). A function f (x) increases on an interval I if f (b) ≥ f (a) for all b > a, where a,b in I. If f (b) > f (a) for all b>a, the function is said to be strictly increasing. x³ is not strictly increasing, but it does meet the criteria for an increasing function throughout it's domain = ℝ.

Solution. We see that the function is not constant on any interval. The function is increasing where it slants upward as we move to the right and decreasing where it slants downward as we move to the right.

A function f (x) is said to be concave on an interval [a,b] if, for any points x_1 and x_2 in [a,b], the function -f (x) is convex on that interval (Gradshteyn and Ryzhik 2000). Each graph bends upward and is therefore concave up.
