**As the options are missing, I will try to explain you how to find one**


Given function: f(x) =
(4)/(x)


If you plug in the value of x = 0, you will get:

f(x) =
(4)/(0) = \infty


If you approach from the right, the value of f(x) near x = 0 will be +
\infty, whereas if you approach from the left, the value of f(x) near x = 0 will be -
\infty. It means that at x=0, there will be a discontinuity (as shown in only graph attached with the question.) If there is no discontinuity at x=0, you can ignore that option.


Now, if there are multiple graphs having discontinuity at x = 0, you can do the following step:

Plug in the value of x = 4 in the given function.

f(x) =
(4)/(4) = 1


It means that at x = 4, the value of y = f(x) will be +1.

Now Plug in the value of x = -4 in the given function.

f(x) =
(4)/(-4) = -1


It means that at x = 4, the value of y = f(x) will be -1.


Nutshell: The graph having the discontinuity at x = 0, and the y values to be +1 and -1 for x = +4 and x = -4 respectively, will be the correct option.


The graph of f(x) =
(4)/(x) is attached with the answer.
