WebFigure 4.34(a) shows a function f f with a graph that curves upward. As x x increases, the slope of the tangent line increases. Thus, since the derivative increases as x x increases, f ′ f ′ is an increasing function. We say this function f f is concave up. Figure 4.34(b) shows a function f f that curves downward. WebDec 20, 2024 · If a function is decreasing and concave up, then its rate of decrease is slowing; it is "leveling off." If the function is increasing and concave up, then the rate of increase is increasing. The function is increasing at a faster and faster rate. Now consider a function which is concave down. WebWhen a function f (x) is increasing, the slope of the curve i.e. f ' (x) is positive. When a function f (x) is decreasing, the slope of the curve i.e. f ' (x) is negative.

If you have f' (x) = x^2 – 2 + x^ (-2), you need to show this is always greater than or equal to 0, to show it is always increasing. A good way to do this is to spot that it is a perfect square i.e. f' (x) = (x − 1/x)^2.
