Finding Inflection Points & Concavity on a Graph – Second Derivative – Calculus

This calculus video tutorial shows you how to find the inflection point of a graph and an equation both graphically and analytically by finding the second derivative, setting it equal to zero and solving for x. It also shows you how to find the concavity of a function and determine if it’s concave up or concave down using a sign chart on a number line.
