Evaluating a linear function

The video tutorial explains the concept of a function as a relationship between input and output, using the example F(x) = 3x + 2. It demonstrates how to evaluate this function at different values: x=4, x=2/3, and x=a+1. The tutorial covers the steps to substitute values into the function, perform calculations, and simplify expressions, providing a clear understanding of function evaluation.
