Does the table below define Y as a function of X?

Answer:
Explanation:
For a function, an input value, x cannot have more than one output value, y.
Looking at the table, no value of x has the same value of y twice. Thus,
the table defines a function
The domain is the set of all values of x that satisfies the function. Thus,
Domain = [- 1, 3]
The range is the set of all values of y that satisfies the function. Thus,
Range = [- 8, 9]
