Whether the givenrelation represented by the graph is a function or not.
Answer to Problem 18E
The relation represented by the graph is not a function.
Explanation of Solution
Given:
A graph of a relation:
Calculation:
We know that a relationship will be a function, when each input in the domain has exactly one specific corresponding output.
That is for a relation to be a function, one x- value cannot have two y -values, while two x- values can have same y- value.
Upon looking at our given graph, we can see that for
Since there are two outputs for one input, therefore, the given relation is not a function.
