True or False: The inverse of the function 
is also a function.
True or False: The inverse of the function 
Consider the graph of the function 
. It passes the vertical line test, that is if a vertical line is drawn anywhere on the graph it only passes through a single point of the function. This means that 
is a function.
Now, for its inverse to also be a function it must pass the horizontal line test. This means that if a horizontal line is drawn anywhere on the graph it will only pass through one point.
This is not true, and we can also see that if we graph the inverse of 
(
) that this does not pass the vertical line test and therefore is not a function. If you wish to graph the inverse of 
, then you must restrict the domain so that your graph will pass the vertical line test.

Using the formula 
where 
is the vertical shift, we have to perform a transformation of moving the function 
up two units on the graph.

Which of the following is the correct graph and range of the inverse function of 
First, we must solve for the inverse of 
So now we are trying to find the range of and plot the function 
. Let’s start with the graph of

True or False: The domain for 
will always be all real numbers no matter the value of 
or any transformations applied to the tangent function.
True or False: The domain for 
This is true because just as the range of

Which of the following is the graph of 
First, we must consider the graph of 
.
Using the formula 
we can apply the transformations step-by-step. First we will transform the amplitude, so 
so we must shorten the amplitude to

Now we must apply a vertical shift of one unit since 
. This leaves us with our answer.
