I recently had this circle on a test and I got the range wrong. My answer for the domain was [-1, 3] which she seemed to have marked correct and my answer for the range was [1, -2] which she marked wrong.
I made a makeshift graph here: http://img.photobucket.com/albums/v471/Rathi04/graph.jpg
Any help is appriciated, and note that the graph is not using decimals or anything that exact.

ah, that makes sense now. I was treating it as an exact point going over 1 and then down 2. Thanks a ton.

your range is incorrect because the top of the circle is not in over the x axis which would make it positive. It is below the x axis so it should start with a negative value.
The value is hard to read but i would say its a (-0.25, -2)
Hope that helps

Only functions have domains and ranges. A circle is not a function.

Yes, that is wrong. Domain is the X value and the Range is the Y value. It should have been [0, -2].
