Answer:
No, the table is not a function since it takes the input -2 to the outputs 2 and -3 (the input -2 does not have a unique output)
Explanation:
A function is a rule that defines a relation between one variable and another.
For something to be a function, it is required that for a given input, you get a unique output.
Hence, in our case, we see that for the input -2, we can either get 2 or -3,
SO, the output is not unique (The answer is not unique it could be 2 or -3)
Hence the table is not a function
