Answer:

No, the given is not a function.

Explanation:

I am confused if the last half of the numbers belong to a y value or not, but the answer is the same regardless.

If all numbers provided are "x", then no; the given does not represent a function. This is because the "x" value has duplicates, which indicates a non function.

Even if the last 5 numbers belong to f(x), or "y", the given is still not a function. the duplicated number is "9", and the 9's would be an x value regardless of the form of the given information.
