El conjunto de parejas ordenadas que no es una función es:
Alternativa C: {(-2,1),(-1,0),(0,1),(-1,2),(2,2)}
Una función se define como un conjunto de parejas ordenadas (x, y) donde no se repite el valor de "x" (corresponde al dominio de la función)
En el caso específico del ejercicio, la alternativa C no corresponde con una función ya que tienen dos parejas con el mismo valor de "x": {(-2,1), (-1,0), (0,1), (-1,2), (2,2)}
Estos pares están en negrita, y el valor repetido subrayado.
