#-# sign signifies an inverse graph of tangent graph

2 signifies the graph amplitude or the #y# values are of two times larger than a normal tangent graph

#4theta# signifies 4 repeats of the normal tangent graph in a #2pi# or 360degrees cycle

In your case, you need to plot 2 cycle of y.
Since 4 cycle in 2#pi#
1 complete cycle in #2pi/4=pi/2#

divide #pi/2# into four parts for each of the four parts of graph which starts at 0.

Explanation:

graph{y=-2tan (4x) [-10, 10, -5, 5]}
