Question

Which of the following functions have a range of all real numbers? Check all that apply.​

Answer 1

A trigonometry rule  is the range of Tangent is all real numbers

The answer would be y = tanx and y=cotx

Answer 2

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:

$y = csc x$

$y = tanx$

$y = cotx$

$y = sec x$

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 $\pi$.
