Inflection Value

The x value p of point (in the domain of f) at change its concave to the opposite concavity (so not between f’’(x)=0).

Point of Inflection

The points that exist at the inflection value in function f. (p, f(p))

Possible Inflection Value (p.i.v)

of a function f(x), is an x-value in the domain of f(x) such that either f"(x) = 0 or f"(x)= DNE .(?) These values are essentially critical values of f'(x)… In comparison with Critical Values and Point with theorems of f(x).

<aside> 💡 Concavity can change at a discontinuity, such as a VA, but it won't be an inflection point.

An inflection value can only occur at a p.i.v. but not all p.i.v. is a inflection value.
