Which ordered pair (x, y) makes the relation below a function? {(0, 1), (-2, 3), (-4, 3), (x, y)}

Alina fully simplifies this polynomial and then writes it in standard form. xy2 – 2x2y + 3y3 – 6x2y + 4xy2 if alina wrote the last term as 3y3, which must be the first term of her polynomial in standard form? xy2 5xy2 –8x2y –2x2y
