Question

30 POINTS
Determine whether the relation shown is a function. Explain how you know

Answer 1

It is not a function

Explanation:

The plot shows (1, 1) and (1, 3) are both defined by the relation. It does not pass the "vertical line test", which requires the relation be single-valued everywhere.

Answer 2

Answer: No, it is not a function.

Explanation:

A function is when the X values don’t repeat, and in this graph, the X values didn’t repeat (there wasn’t two points on the X values) so it is not a function.
