Determine the extrema using EVT of a rational function

The video tutorial explains the product rule in calculus, demonstrating how to find critical values by setting the function to zero or identifying when it is non-differentiable. It discusses the extreme value theorem by testing endpoints and critical values, and analyzes when the function becomes undefined, emphasizing the importance of critical values.
