Question

Is the table shown a function? yes or no

Answer 1

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
