For Exercises 1-2, determine if the relation defines
Whether the relation given in the graph defines
Answer to Problem 1RE
The relation given in the graph does not define
Explanation of Solution
Consider the function
If no horizontal line intersects the graph from the function
Consider the graph. Draw horizontal lines in the graph.
Here, the horizontal line intersects the graph at more than one point.
Therefore, the relation given in the graph does not represent a one-to-one function.
