Answer:

Option 2 and 4

Step-by-step explanation:

Given : Function's graph has asymptotes located at the values x=\frac{\pi}{2}\pm n\pi

To find : Which function graph has asymptote given?

Solution :

An asymptote is a line or curve that approaches a given curve.

To find vertical asymptote the limit has to go to either  ∞  or  − ∞  , which happens when the denominator becomes zero.

The sine are defined for all real x, y is defined for all real x, so there are no vertical asymptotes.

So, Option 1 is not true.

In option 3,

y=\cot x=\frac{\cos x}{\sin x}

When we put Denominator = 0

\sin x=0

Value of x lie between (0,n\pi)

So, Option 3 is not true.

In Option 2,

y=\sec x=\frac{1}{\cos x}

When we put Denominator = 0

\cos x=0

When cos x=0 the values of x is

x=\pm\frac{\pi}{2},\pm\frac{3\pi}{2},\pm\frac{5\pi}{2},.....

x=\frac{\pi}{2}\pm n\pi

Therefore, The graph of y= sec x has asymptote located at the values x=\frac{\pi}{2}\pm n\pi

So, Option 2 is correct.

In Option 4,

y=\tan x=\frac{sin x}{\cos x}

When we put Denominator = 0

\cos x=0

When cos x=0 the values of x is

x=\pm\frac{\pi}{2},\pm\frac{3\pi}{2},\pm\frac{5\pi}{2},.....

x=\frac{\pi}{2}\pm n\pi

Therefore, The graph of y= tan x has asymptote located at the values x=\frac{\pi}{2}\pm n\pi

So, Option 4 is correct.

Therefore, Option 2 and 4 are correct.

Hence Option A is correct - 2 only
