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

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

The answer would be y = tanx and y=cotx

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 .

y = - 6

step-by-step explanation:

given the point (- 2, y) lies on the graph then it is a solution of it's equation.

substitute x = - 2 into the equation for value of y

y = 3(- 2) = 3 × - 2 = - 6

the point on the graph is (- 2, 6)

i don't have the answer rn but go to math papa. it shows the steps and the answer. hope this : )
