Exercise 1 Page 156

If a relation is a function, how many y-values can any one x-value have?

Yes, see solution.

Practice makes perfect

For a relation to be a function, each x-value can only be paired with one y-value, but one y-value can be paired with multiple x-values. (0,1), (5,6), (7,9) Examining the ordered pairs, we can see that there is no x-value with multiple y-values. Therefore, the relation is a function.
