What are the domain and range of y = tan X? Select one choice for domain and one for range.
A. Range: -1 B. Domain: 2 + + na
O C. Domain: All real numbers
O D. Range: All real numbers

From photo you would choose B and D.
Your options make no sense.

tan(x) = sin(x) / cos(x) so the domain is restricted by excluding x where cos(x) = 0
This happens when x = pi/2 and repeats every pi after that = pi/2 + n x pi where n is an integer
I don’t like the wording of B but it is the best definition of domain in the question.
