Option A {(1, 2), (6, 2), (−3, −3), (2, 0)} represents a function.

A function is a relation where each input is associated with exactly one output. To determine whether a set of ordered pairs represents a function, we need to check if any input is repeated with different outputs.

From the options provided:

Option A: {(1, 2), (6, 2), (−3, −3), (2, 0)} - This is a function because each input is associated with exactly one output.

Option B: {(8, 9), (-6, -9), (−3, −2), (−3, −5)} - This is not a function because the input (-3) is repeated with different outputs (-2 and -5).

Option C: {(-2,-2), (7, 8), (−7, −2), (3, 2)} - This is a function because each input is associated with exactly one output.

Option D: {(6,-5), (0,7), (−1, −1), (0, 6)} - This is not a function because the input (0) is repeated with different outputs (7 and 6).

Therefore, option A {(1, 2), (6, 2), (−3, −3), (2, 0)} represents a function.

The probable question may be:

Which set of ordered pairs represents a function?

Answer

A {(1, 2), (6, 2), (−3, −3), (2, 0)}

B {(8, 9), (-6, -9), (−3, −2), (−3, −5)}

C {(-2,-2), (7, 8), (−7, −2), (3, 2)}

D {(6,-5), (0,7), (−1, −1), (0, 6)}
