To determine

## To sketch: The function y=tanx by hand without plotting any points and then graph of the function y=14tan(x−14) .

Expert Solution

### Explanation of Solution

The standard graph of the function y=tanx is roughly drawn as shown below in Figure 1.

Then, draw the graph of y=tan(x14) , shift the graph y=tanx by π4 units to the right. Thus, the graph of y=tan(x14) is shown below in Figure 2.

From Figure 2, it is observed that Figure 1 is shifted π4 units to the right. Then, draw the graph of y=14tan(x14) , shrunk the graph y=tan(x14) vertically by a factor of 4. Thus, the graph of y=14tan(x14) is shown below in Figure 3.

Observe that Figure 3 is obtained from Figure 1 in such a way that it is shifted π4 units to the right and then compressed vertically by a factor of 4.
