Çözüldü Trigonometric Function Graph - Vertical Asymptotes

https://i72.servimg.com/u/f72/19/97/10/39/trigo158.png

Solution without needing to know the graph of tan(x):
Since the vertical asymptotes are x = ∓π, the limits of the function for these values must be ∓∞, so the choices A, C, D, E are immediately eliminated.

The solution in the book:
"(B) The figure shows the graph of y = tan(x) shifted 2 units down with a period of 2π. The correct equation is y = tan(x / 2) - 2."
