3.2 - Local & Absolute MAX & MIN Points (full lesson) | grade 12 mcv4u | jensenmath.ca

In this lesson you will learn how to use the first derivative test to find local max/min points of a polynomial function. A local max exists at a point if at the point, the derivative is zero, before the point the derivative is positive (function increasing), and after the point the derivative is negative (function is decreasing). A local min exists at a point if at the point, the derivative is zero, before the point the derivative is negative (function decreasing), and after the point the derivative is positive (function is increasing). When finding an absolute max or min, test endpoints of interval and critical numbers.

Thank you, as always critical problems to choose to eliminate all ambiguities between local and absolute extrema. In particular I enjoyed example one, very simple but very effective way of telling me how to think about the differences!! Cheers Jensen.
