The graph of is the graph of is streched vertically by a factor of .

The period of the function is .

Find vertical asymptotes.

Tangent function has asymptotes equations:  and .

Hence the vertical asymptotes are  and .

Table :

Construct a table containing -intercepts and intermediate points for for one period .

 Function vertical asymptote intermediate point x-intercept intermediate point vertical asymptote

Graph:

1. Draw a coordinate plane.

2. Plot the coordinate points.

3. Then sketch the graph of , connecting the points with a smooth curve.

Graph of the function is
