whether the given relation is a function.

Answer to Problem 12SGR
Yes, the relation is a function.
Explanation of Solution
Given:
Year | ‘02 | ‘04 | ‘06 |
Cost ($) | 1.36 | 1.82 | 2.26 |
Calculation:
Consider the table that shows cost of gas in different years:
Year | ‘02 | ‘04 | ‘06 |
Cost ($) | 1.36 | 1.82 | 2.26 |
The relation is said to be function if each domain value is paired with only one range value.
Since, in the given table the cost is different in different years.
Conclusion:
Therefore, the relation that shows the cost of gas in different years is a function.
