The polinomials can only have exponents positive integers, that is: 1, 2, 3, 4, 5, 6, ... (you can include the 0 also, because iis is the term independent).Therefore, if you say that one of the terms of the polynomial 9-x ^ (something negative), it is necessary that the number after the negative sign to be negative, because negative times negative is positive.Therefore, the only possible choice of the response options is option 3) -9.Answer: 3) - 9
