Answer:
This graph does not represent a function.
Step-by-step explanation:
A function is defined as a set of values that have one output (y-value) for each input (x-value). In other words, each x-value should only ever correspond with a single y-value. In this graph, there are multiple y-values for the x-values between ~-2 and ~12. Another piece of evidence that this is not a function is that there are many inputs that have no output. This makes this graph a relation rather than a function.
