Exercise 37 Page 182

If a relation is a function, how many y-values can each 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. (3,6), (4,8), (5,10), (6,9), (7,14) Examining the ordered pairs, we can see that there is no x-value with multiple y-values. Therefore, the relation is a function.
