Follow the seven step strategy to graph the following rational function. 7x f(x) = X2 - 16 To graph the function, first determine the symmetry of the graph of f. Choose the correct answer below O origin symmetry O y-axis symmetry O neither y-axis symmetry nor origin symmetry What is the y-intercept? Select the correct choice below and, if necessary, fill in the answer box to complete your choice O A. The y-intercept is (Type an integer or a simplified fraction ) O B. There is no y-intercept What is/are the x-intercept(s)? Select the correct choice below and, if necessary, fill in the answer box to complete your choice O A. The x-intercept(s) is (Type an integer or a simplified fraction. Use a comma to separate answers as needed ) O B. There is no x-intercept
