# What is the domain and range of #y= 3 tan x#?

##### 1 Answer

Domain:

Range:

#### Explanation:

graph{3tanx [-10, 10, -5, 5]}

As we can see from the graph, there are recurring vertical asymptotes, and this means that the function is not defined at these points. So we need to find these points and exclude them from our domain.

To do this, we will take help of the

Now we know all the points where our function isn't defined, so we know the domain must be:

Now for the range. We see that the all of the sections between the vertical asymptotes go from
