Calculus I - 3.4.1 Intervals of Concavity and Points of Inflection

Now that we are familiar with the process of finding the intervals of increase or decrease by the sign of the derivative function, we repeat the process for the second derivative. This will tell us if the slope of the tangent line is increasing or decreasing, which tells us if the original function is concave up or concave down.
