Choose the function whose graph is given by

A) tan(x-) - 1

Step-by-step explanation:

We are required to find the function whose graph is given.

Now, we know that 'tanx' has this type of graph.

After applying the changes to tanx provided in the options, we see that this graph is of tan(x-) - 1.

We can see below that after plotting tan(x-) - 1, its graph is same as that of the graph given to us.
