Which graph shows the solution set of 

Hence final answer is .

correct choice is D because both ends are open circles.

Step-by-step explanation:

Given inequality is

Setting both numerator and denominator =0 gives:

x-1=0,  x-3=0

or x=1, x=3

Using these critical points, we can divide number line into three sets:

, and

We pick one number from each interval and plug into original inequality to see if that number satisfies the inequality or not.

Test for .

Clearly x=0 belongs to interval then plug x=1 into

Which is False.

Hence desn't belongs to the answer.

Similarly testing other intervals, we get that only satisfies the original inequality.

Hence final answer is .

correct choice is D because both ends are open circles.
