Question

What is the domain of y = tan x? A. (–∞, ∞) B. C. all D. all

Answer 1

Given:

The function is

$y=\tan x$

To find:

The domain of the given function.

Solution:

We know that, domain is the set of x-values or input values.

We have,

$y=\tan x$

$y=\dfrac{\sin x}{\cos x}$

The functions sin x and cos x are defined for all real values of x. So, the function tan x is defined for all real values of x except those value for which cos x = 0.

So, domain is $-\infty$.

Note: All options are incorrect.

Answer 2

Answer:

C

Step-by-step explanation:

all x≠pi/2+pi n
