**Domain :** **in radians.
Range: All reals**

#### Explanation:

The domain is the values that x can take in the function. The

tangent functions have vertical asymptotes (at the end of every

period) and x has no values at these points, but does exist

everywhere else. So domain is as

Domain :

Range : Tangent functions have no maximums or minimums, so the

range for a tangent function is all reals. [Ans]
