Understanding the Function f(x) = x / (x + 3) + 4

The video tutorial explains how to calculate function values for f(x) = x / (x + 3) + 4. It covers the calculations for f(0), f(3), f(-2), and f(-3), demonstrating how to substitute values into the function and simplify the results. The tutorial highlights that f(-3) is undefined due to division by zero and provides guidance on graphing the function's points.
