To describe and correct:
The error in the given statement.
Answer to Problem 7E
The given relation is a function becausetwo x- values can have same out-put.
Explanation of Solution
Given:
A statement: The relation
Calculation:
We know that a relationship will be also a function, when each input in the domain has exactly one specific corresponding output.
We also know that for a relation to be a function, one x- value cannot have two y -values, while two x- values can have same y- value.
Since 1 and 2 represent two different x -values (inputs), so they can have the same outputs.
Therefore, our given relation is a function.
