I need help with this here is the question:

Use the real zeros of the numerator and denominator of R to divide the x-axis into intervals. Determine where the graph of R is above or below the x-axis by choosing a number in each interval and evaluating R there. Select the correct choice below and fill in the answer box(es) to complete your choice

A. The graph of R is above the x-axis on the interval(s)
and below the x-axis on the interval(s)
(Type your answers in interval notation. Use a comma to separate answers as needed.)

B. The graph of R is below the x-axis on the interval(s)
(Type your answer in interval notation. Use a comma to separate answers as needed.)

C. The graph of R is above the x-axis on the interval(s)
(Type your answer in interval notation. Use a comma to separate answers as needed.)
