Answer:
C) Yes, there exists one output for every input.
Step-by-step explanation:
We are given a graph.
When we draw vertical line test, the line passes through the one only point of the graph.
Similarly, when we draw horizontal line test, the line passes through the one only point of the graph.
The graph hold true for both vertical line test and horizontal line test.
Therefore, it is an one-one function.
For every input, there exists an output.
Therefore, the answer is C) Yes, there exists one output for every input.
