Evaluating Definite Integrals and Functions

The video tutorial explains how to evaluate a definite integral using a geometric approach. It begins by defining the function and interval, then graphing the absolute value function to identify key points. The area under the graph is calculated using triangles, leading to the final integral result. The tutorial emphasizes understanding the relationship between the graph and the integral.
