Which set below is the domain of {(2, -3), (-1,0), (0, 4), (-1, 5), (4, -2)}?
A. {-3,0,4,5,-2} B.{2, -1, 4} C.{-3, 4, 5, -2} D.{2, -1, 0, 4}

I don't need a fast answer, I need a thorough explanation, I am trying to advance in Math and I am learning on my own. I want to learn how to do this correctly. Thank you in advance, I Promise I will give brainliest if I am satisfied! (100 points just so you see you are loved (: )

Answer:

D

Step-by-step explanation:

We have the set:

[tex]\{(2, -3), (-1,0), (0, 4), (-1, 5), (4, -2)\}[/tex]

Remember that the domain for a set of values is simply the input values.

In other words, our domain will be all of our x-coordinates.

We can see that our x-coordinates are: 2, -1, 0, -1, and 4.

So, our domain is:

[tex]\{2, -1, 0, 4\}[/tex]

Note that we only write need to write the -1 once.

So, our answer is D.

And we're done!
