Hurry you analyze the function f(x) = - 2 cot 3x. include: - domain and range - period - two vertical asymptotes

Domain
All Real Numbers except with sin(3x)=0, i.e.,
All Real Numbers except x = 0 or pi/3 etc

Range::: All Real Numbers

- Period = (2pi/3) = (2/3)pi
-
- Two Vertical Asymptotes:: x = 0 and x = pi/3

Domain is all real numbers except npi/3 for all integers, n. 
Range is all real numbers. 
Period is pi/3. 
Two vertical asymptotes are x = pi/3 and x = 2pi/3.

This is what i found “an explicit formula designates the nth term of the sequence, as an expression of n (where n = the term's location). it defines the sequence as a formula in terms of n. this example is an arithmetic sequence(the same number, 5, is added to each term to get to the next term).” i hope this you for what your looking for. can you plz mark me brainliest?
