Answer:
The correct answer option is tan x and cot x.
Step-by-step explanation:
We are given the following functions and we are to determine whether which of them have a range of all real numbers:
[tex] y = csc x [/tex]
[tex] y = tanx[/tex]
[tex] y = cotx [/tex]
[tex] y = sec x [/tex]
Range is the values of y which a function can take so range of tan x and cot x are all real numbers.
Period of tan x and cot x is [tex] \pi [/tex].
