WebJun 16, 2024 · If the number is positive this means the function is increasing and if it's negative the function is decreasing. I picked 0 a number from the left f '(0) = 4 This means from (∞,1) the function is increasing. Then I picked a number from the right which was 2. f '(2) = −4 This means from ( −1,∞) the function is decreasing. WebThus, since the derivative increases as x increases, f ′ is an increasing function. We say this function f is concave up. Figure 4.34 (b) 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 ′ is a decreasing function.
