Hey guys i reallly need some < 3
the graph shows two lines, m and n.
how many solutions are there for the pair of equations for lines m and n? explain your 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:

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 .
