From the given table,
Each x value s assigned to exactly one output y value.
Hence, it is a function of x.
We know that the domain of the function is a set of all input values.
The domain of the function is, {-1, 0, 1, 2, 3}.
We know that the range of the function is a set of all output values.
The range of the function is, {-5, -4, 2, 5, 9}
Therefore, the answer is,
Yes, D={-1, 0, 1, 2, 3}, and R={-5, -4, 2, 5, 9}
