Answer:

See below.

Explanation:

Tangent functions are in the form:

#y=a*tan(b(x-c)) + d#

where #a# is any vertical stretch or compression, #b# is any horizontal stretch or compression, #c# is any horizontal shift, and #d# is any vertical shift (note that there is no amplitude since this is a tangent function).

One thing to note in your case is that tangent functions always have a range of all real numbers.

I hope that helps!
