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

The correct answer option is tan x and cot x.

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`.
