Answer:
No
Step-by-step explanation:
First step:Ask yourself what is a function
The answer to this would be: a function is a relation in which each element in the domain is mapped on to one AND ONLY one element in the co-domain.
This definition simply means that if it a function, each x value is mapped on to one and one one y value.
When we look at the coordinates given, all the x values are mapped onto the same y values hence it is not a function
