Algebra-2

For a polynomial function , the possible rational zeros are of the form , where  is a factor of the constant term  and  is a factor of the leading coefficient .

For the function , the leading coefficient is 9 and the constant term is -11.

The factors of -11 are ±1 and ±11.

The factors of 9 are ±1, ±3, and ±9.

So, the possible rational zeros are , where  is a factor of -11 and  is a factor of 9.
