Graphing a basic quadratic function using a table

This video tutorial demonstrates how to graph the quadratic equation y = 1/2x² using a table of values. The instructor explains the process of setting up a table with selected x-values, calculating the corresponding y-values, and plotting these points on a graph. The tutorial emphasizes the symmetry of the parabola and the importance of choosing values that simplify calculations. The video concludes with drawing the parabola and indicating its extension to infinity.
