@Standish we are here to help, dont just give answers. It is against the rules. especially when you see someone typing..
{(2, –3), (4, 6), (3, –1), (6, 6), (2, 3)} The above list of points, being a relationship between certain x's and certain y's, is a relation. The domain is all the x-values, and the range is all the y-values. To give the domain and the range, I just list the values without duplication: domain: {2, 3, 4, 6} range: {–3, –1, 3, 6}
domain is all the x values we are allowed to use, is there any x value we cant use?
i have never learned this so it is new to me so i don't know
Well, just try out different X and Y values and you come to see that the domain and range is endless! try it out for yourself!
Its all because its a linear equation/graph:) Goes on up and down forever!
