What are you trying to do? Fit the data to a line or curve? Please be more specific - post all the details of the question.

What are you supposed to do with these values?

I have to identify the domain and range of the function. that's all it says.

The domain is an interval starting from the smallest defined value for x and goes up to the largest defined value for x.

The range is an interval starting from the smallest defined value for y and goes up to the largest defined value for y.

Can you answer this question now? What do you think the domain and range are?

THANK YOU!!!!!!!!!!!!!

I think "domain" is the set of all possible inputs, and "range" is the set of all possible outputs. So they are not necessarily "intervals".

So in this particular problem, the domain is {0,1,2,3}, and range is {5,7, 15, 44}.

Thanks, but I got it. I was reading the textbook and then it sort of clicked. Is'nt it weird how that sometimes happens? Anyway, Thanks everyone a WHOLE LOT.

It never ceases to amaze me how people will think they should be some trick or method to solve a problem in which they don't know the meanings of the words!

This problem is simple as long as you know the definitions of "domain" and "range".

Silverstaraptor, the first thing you should have done was look up "domain" and "range" in your textbook.
