How do you do this and what is the correct answer? simple and concise explanation !

Step-by-step explanation:

This is a neat question. I suggest that you graph it on desmos. You will lean a bunch by doing it. These are the graphs you should put on there.y = 1/(abs(x - a) - 1):In redWhen you use your down arrow, a new entry will be given you. You can use your mouse to operate the slider you get when you type a = 5so your next graph should be a = 5Use your down arrow again. Put in x = 4: Blue LineUse your down arrow again. Put in x = 6: Green Line

Be patient with this. Play with the sliders to see what they do. I believe you are correct, but I am not certain of the second union although it does look correct.

The graph I have enclosed is of what I have described in the steps above. Make sure you try it all out.
