Answer:

A. {(-1, 2), (1, 3), (1, 5), (-3, 4)}

Step-by-step explanation:

1. A function can have x-values with many different y-values, but two same x-values cannot have different y-values.

  • Example of function: {(1, 2), (2, 2)}
  • Example of not function: {(1, 2), (1, 3)}

2. Given the information above, A. {(-1, 2), (1, 3), (1, 5), (-3, 4)} is correct/not a function because the x-value of 1 has two different y-values in the ordered pairs (1, 3) and (1, 5).
