Transformations of the tangent function

The video tutorial explains how to determine the period of a function, graph it without shifts, and identify asymptotes. It covers the calculation of the period using the reciprocal of the coefficient, graphing the function, and identifying vertical and horizontal transformations. The tutorial also discusses determining the domain and range, focusing on asymptotes and their implications.

How does the teacher suggest to graph the initial function?
