Intervals of concavity and inflection points
WebAn inflection point only requires: 1) that the concavity changes and. 2) that the function is defined at the point. You can think of potential inflection points as critical points for the … Web5.4 Concavity and inflection points. We know that the sign of the derivative tells us whether a function is increasing or decreasing; for example, when f ′ ( x) > 0 , f ( x) is increasing. The sign of the second derivative f ″ ( x) tells us whether f ′ is increasing or decreasing; we have seen that if f ′ is zero and increasing at a ...
