Determine whether the following statement is true or false. The expression x5 - 9v x + 1 is a polynomial of degree 5. A The statement is true because for this expression, the largest exponent on x is 5. B The statement is false because the smallest exponent is the degree of a polynomial. C The statement is false because for a polynomial, the exponent of x should always be greater than 1. D The statement is false because for a polynomial, all exponents on x need to be positive integers or zero
