The question is in the picture
1 answer:
The answer is C. When a question asks for the domain and range of a table you can translate that to finding the x and y coordinates of the relation. The example above has already identified the x and y values, so now all you have to do is put them in order from least to greatest. If you've done everything correctly you will have the answer choice C.

I suppose that you should have given some pairs to choose from.
Anyway, I can tell you how to do it. Given a pair , you have to substitute
and
to
and
respectively, and see if you get something true.
For example, the pair satisfies the function, because the substitution yields
which is true. On the other hand, the pair doesn't satisfy the function, because
is clearly false.
