AP Calculus BC Review April 8th

Today I studied the first and second derivative tests. The first derivative test is used to find the intervals in which the function is increasing/decreasing. The second derivative test is then used to calculate a curve's concavity and the values of any relative extrema. Lastly, the point of inflection determines where a graph changes concavity. To find this point, you must set the second derivative equal to "0" and solve.
