Select all the correct answers. Which functions have a range of
{y € R |- 12 + 71 – 9
of(1) = ſr – 8
o(t) = -4r + 11
O f(t)
of(x) = -(x + 1)2 – 4
21+3

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 .
