Calculus I: The Product Rule (Level 3 of 3)

The video tutorial explains how to find the derivative of a function formed by the product of two functions using their graphs. It covers two examples: finding the derivative at x=1 and x=4. The tutorial emphasizes the use of the product rule and the geometric interpretation of derivatives as slopes of tangent lines. It guides viewers through identifying function values and slopes from graphs to calculate derivatives.
