Exercise 7 Page P5

How would you go about finding the values in each ordered pair from the graph?

Ordered pairs: (-1,-3), (0,-2), (1,-1), (1,2), (2,3), (3, 4)
Domain: {-1,0,1, 2, 3}
Range: {-3,-2,-1,2,3,4 }
No, it isn't a function.

Practice makes perfect

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. (-1,-3), (0,-2), ( 1, -1), ( 1, 2), (2,3), (3, 4) Examining the ordered pairs, we can see that there is at least one x-value with multiple y-values. Therefore, the relation is not a function. The domain of a relation is found by listing the relation's x-values. The range is found by listing the relation's y-values. Domain:& {-1, 0, 1, 2, 3 } Range:& {-3, -2, -1, 2, 3, 4 }
