Final answer:
To determine which of the given options is not a factor of f(x), we need to divide f(x) by each option and check if the remainder is zero.
Step-by-step explanation:
To determine which of the given options is not a factor of f(x), we need to check if each option can be divided evenly into f(x). If the remainder is zero for all options, they are factors of f(x). If the remainder is not zero for any option, that option is not a factor of f(x).
We can use long division to divide f(x) by each option. If the remainder is not zero, then that option is not a factor of f(x).
In this case, the options are not provided, so I cannot determine which one is not a factor of f(x).
