Graph all six basic trigonometric functions.
Specify tangent zeros, asymptotes, and branches on an interval
Problem
Use the graph of \(y~=~\tan(x)\) on \([-\pi~,~0]\) to state the period, all zeros, vertical asymptotes, defined branches, monotonicity on each branch, and range.

A
The period is pi; zeros are -pi, 0; vertical asymptotes are -pi/2; defined branches are [-pi, -pi/2), (-pi/2, 0]; tangent is strictly decreasing on every branch and has range (-infinity, infinity).
B
The period is 2pi; zeros are -pi, 0; vertical asymptotes are -pi/2; defined branches are [-pi, -pi/2), (-pi/2, 0]; tangent is strictly increasing on every branch and has range (-infinity, infinity).
C
The period is pi; zeros are -pi, 0; vertical asymptotes are -pi/2; defined branches are [-pi, -pi/2), (-pi/2, 0]; tangent is strictly increasing on every branch and has range [-1, 1].
D
The period is pi; zeros are -pi, 0; vertical asymptotes are -pi/2; defined branches are [-pi, -pi/2), (-pi/2, 0]; tangent is strictly increasing on every branch and has range (-infinity, infinity).
