Functions/Equations/Arithmetic Sequences

Graph the equation f(x) = -3x + 1 for x values:

-1, 0, 1, 2

Amy and Amia were having a discussion about the relation on the left. Amy says that it is a function because none of the x value repeat.

Amia says it is not a function because one of the x values do repeat. Who do you agree with?
