K Follow the steps for graphing a rational function to graph the function G(x)= X x-4 If needed, first write the given function as a single rational expression. Then factor the numerator and denominator of G(x). Select the correct choice below and, if necessary, fill in the answer box within your choice. 1x A. G(x)= (Type your answer in factored form. Do not simplify.) (x+2)(x-2) OB. G(x) cannot be factored further. What is the domain of G(x)? Select the correct choice below and, if necessary, fill in the answer box within your choice. OA. {xlx (Type an integer or a simplified fraction.) OB. {xx (Type an integer or a simplified fraction. Use a comma to separate answers as needed.) OC. {xx
