Question

Which set of ordered pairs represents a function? {(2,-2),(1,5),(-2,2),(1,-3),(8,-1)}

Answer 1

First option is correct

Explanation:

The set of ordered pairs that represents a function is:

{(2,-2),(1,5),(-2,2),(8,-1)}

To check if a set of ordered pairs represents a function, we need to make sure that each input (x) has only one output (y). In this set, each x-value (2, 1, -2, and 8) has a unique y-value (-2, 5, 2, and -1), so this set represents a function.

The ordered pair (1, -3) in the original set does not belong to this set, because the x-value 1 has two different y-values (-3 and 5), so it violates the definition of a function.
