Answer:
The first one because every x value can only have one y value
Step-by-step explanation:
The set of ordered pairs that represents y as a function of x are; {(0, 0), (1, 1), (2, 3), (3, 3)}
We must be aware that, dependent variable, y can only be a function of x if;
For every value of x, there must only be one value of y.
In essence,
For case 1:
- y is a function of x, because for every value of x, there's only one value of y.
For Case 2:
- y is not a function of x, because there's two values of y for a value of x.
For Case 3:
- y is not a function of x, because there's two values of y for a value of x.
For Case 4:
- y is not a function of x, because there's two values of y for a value of x.
