How to graph a parabola in vertex form with a vertical compression

The video tutorial explains how to identify the axis and vertex of a parabola, plot the vertex, and understand the graph's orientation based on the value of 'a'. It covers choosing appropriate values for graphing a stretched parabola and calculating points to ensure integer values. The lesson concludes with reflecting points over the axis of symmetry and emphasizes the ease of finding the vertex in vertex form.

Why is it preferred to use integer values when choosing points for the graph?
