Select the correct choice below and, if necessary, fill in the answer box(es) to complete your choice. O A. The graph will cross the x-axis at x = and touch but not cross the x-axis at x = (Type integers or simplified fractions. Use a comma to separate answers as needed. Type each answer only once.) O B. The graph will touch but not cross the x-axis at x (Type an integer or a simplified fraction. Use a comma to separate answers as needed. Type each answer only once.) O C.
