Answer:
Option C is the correct choice that is
Step-by-step explanation:
As this is a multiple choice question we will reduce the options and work on it with the given points
Note:We know that where there is
sign associated with it have a straight line graph there is no breaking in the line.
And when there is simply we have a dashed line when we plot it on a graph.
So option B and D are discarded.
Now one-by one we will put the values to know which equation it satisfies.
If we put then
.
So working with option A.
Plugging the values.
And we know that must be equal to
so this is not the right answer.
We are left with only one choice that is C .
So option C is the correct option of the above inequality.
