"Graphing" is just plotting calculated values of y for a list of x.

Explanation:

Set up a table with various "x" values. Calculate the corresponding "y" values and then plot them on a graph, or use a spreadsheet or plotting program.

In this case, we know that the cosine function is regular and periodic. One full cycle looks like any other. The "#2/3#" factor applied will simply reduce the amplitude of the function.
