Ok, i have a bunch of graphes with a line......
like one for a visual aid....
thes are to rays at the point (-3,2)
one goes down and one goes up....
what is the domain and range and how do you find it
i got the domain as 2 and the range as -3

the domain is always the x-coordinate (-3) and the range is always the y-coordinate (2).

The domain is ALL the x's that are used in this graph--not just the one point, but any x-values that the rays pass through.
Similarly the range is ALL the y's that are used.
It's hard to visualize what you're describing, but almost certainly you have a lot of numbers, and quite possibly all real numbers for either or both of the domain and the range. If the rays go STRAIGHT up and straight down from the single point (essentially making a vertical line), the domain would be just -3, and the range would be all real numbers.

seems if the definition of a function is "for each x there is in basic terms one y." finding are your ordered pairs, your area is the values of x (or your first form in each ordered pair):4, a million, 3, 6 Now, contemplate whether there are 2 of the comparable first numbers with a distinctive y. you have 2 ordered pairs that have the comparable y yet they have distinctive x values so your relation is a function. Your selection is the y values, 2, 3 and four
