Understanding Derivatives and Function Changes

The video tutorial explains how to determine the minimum and maximum possible values of f(8) - f(2) given that the derivative f'(x) is between 3 and 5 for all x. It demonstrates the calculations by assuming constant derivative values of 3 and 5, showing how these affect the slope and the resulting function values. The tutorial uses graphical representation to illustrate the changes in y as x changes, providing a clear understanding of the problem and solution.
