Evaluating Function Values and Expressions

The video tutorial guides viewers through the process of graphing a polynomial function, specifically p(x) = x^2 - 5x + 6. It covers setting up the graph with appropriate x-values, calculating corresponding y-values, plotting these points, and drawing the resulting parabola. The tutorial emphasizes the importance of using a consistent scale and identifies the zeros of the polynomial by observing where the graph intersects the x-axis.
