To find the x-coordinate of a point, we move vertically until we hit the x-axis. Similarly, to find the y-coordinate, we move horizontally until we hit the y-axis.
Now let's list the ordered pairs that we found. (2,4),(8,8),(14,12) The domain of a function is found by listing the relation's x-values. The range is found by listing the relation's y-values. Domain: Range: {2,8,14}{4,8,12}
