Domain is the input and/or x Range is the output and/or y So to find the domain you would look for the x axis in a graphed function, the input on a table, or the numbers in a problem that would be on that axis or side of the table. Same for range
Domain and range can be found from the graph ... Domain is the values of x-coordinates and Range are the values of y-coordinates . FOR EXAMPLE: (1,6)(8,2)..... 1 and 8 are x-coordiantes and hence DOMAIN. 6 and 2 are y-coordinates and hence RANGE.
