Answer:

2bc

Step-by-step explanation:

The product of c and b means c X b. However, in algebra, we typically miss out the X (multiply) symbol. We also like to put letters in alphabetical order. So this means the product of c and b is written as bc.

Then, to double a number, this just means to multiply by 2.

so we have 2Xbc. But, again, we don't write in the multiply symbol. We also put numbers in front of letters.

So this becomes 2bc.

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 red
When 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 = 5
so your next graph should be a = 5
Use your down arrow again. Put in x = 4: Blue Line
Use 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.
