function or relation graph examples

So on a standard coordinate grid, the x values are the domain, and the y values are the range. So the second graph represents a function as well! Negative 2 is already mapped to something. When learning to read, we start with the alphabet. So for example, let's say that the number 1 is in the domain, and that we associate the number 1 with the number 2 in the range. Therefore, to compute this using the graph, starting at the origin 0, 0 , we go two units to the right and then go up until we hit the graph. Not every relation is a functional relationship.
