WebThis derivative is increasing in value, which means that the second derivative over an interval where we are concave upwards must be greater than 0. If the second derivative … WebIf a function is decreasing and concave up, then its rate of decrease is slowing; it is “leveling off.” You can see this in the left side of Figure 3.4.2. 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.
WebExamples: Find the open intervals where each function is increasing, decreasing, concave up and concave down. Locate any inflection points. 6. 7. 8. Summary f’(x) f”(x) … WebConcavity relates to the rate of change of a function's derivative. A function f f is concave up (or upwards) where the derivative f' f ′ is increasing. This is equivalent to the …
