Follow the steps for graphing a rational function to graph the function P(x) = 4 X+X+b X+X +6 x-36 A. P(x)= (Type your answer in factored form. Do not simplify.) (x-6)(x+6) B. P(x) cannot be factored further. What is the domain of P(x)? Select the correct choice below and, if necessary, fill in the answer box to complete you choice. OA. {xx < (Type an integer or a simplified fraction.) B. {xx (Type an integer or a simplified fraction.) C. {xx % -6,6} (Type an integer or a simplified fraction. Use a comma to separate answers as needed.) OD. The domain is the set of all real numbers. Write P(x) in lowest terms. Select the correct choice below and, if necessary, fill in the answer box to complete your choice. OA. P(x)= (Simplify your answer.) B. P(x) is already in lowest terms.
