A function is said to be concave upward on an interval if f″(x) > 0 at each point in the interval and concave downward on an interval if f″(x) < 0 at each point in the interval. If a function changes from concave upward to concave downward …f′′(0)=0. By the Second Derivative Test we must have a point of inflection due to the transition from concave down to concave up between the key intervals. f′′(1)=20>0.

Definition of Point of Inflection. A point P P on the graph of y = f (x) y = f ( x) is a point of inflection if f f is continuous at P P and the concavity of the graph changes at P P. In view of the above theorem, there is a point of inflection whenever the second derivative changes sign.The connection between the second derivative and concavity leads to the next series of steps.
