Polynomial function f(x) has roots -4, 2, 1, and
11 what must also be a root of f(x)?

J= r + 9 because since jessica rode 9 more miles than roger, you add 9 miles to rogers mileage.

You move the constant to the right side and change its sign to be 9z= -6 -8. that’s the first step.the second step would be calculate the difference of -8-6 to get -14. you equation should now be 9z=-14the last step is to divide both sides by 9 to get z=-14/9hope this
