Suppose that p(x)is a continuous function whose derivative, p'(x), and second derivative, p''(x), are defined and continuous for all real numbers. Some of the values ofp'(x) and p''(x)are provided in the table below.Assume that the values of both p'(x) and p''(x) are strictly positive or strictly negative between consecutive table entries.On which of the following intervals must p(x)be always concave up? Select all that are correct.A.(3,4)B.(4,5)C.(5,6)D.(6,7)E. None of the above.
