Rolle's Theorem Calculus 1 AB

I introduce Rolle's Theorem and work through two examples. My first diagram in my explanation of Rolle's Theorem, should have labelled function f not g. Part of the video was removed because you can see at 6:44 I wrote x as the square root of x squared, well that is equivalent to the absolute value of x. This did not change my final answer, where is the tangent horizontal, but I inadvertently changed the function. The correct process is displayed in the following scene.
