Extracted text: 20 22 24 26 28 h(x) 10 14 11 17 15 9. The table above gives select values of the function h at selected values of x. If h has exactly two critical points on the open interval (20,28), which of the following must be true? (A) h'(x) = 0 exactly two times in the open interval (20,28). %3D (B) h(x) has exactly two points of inflection in the open interval (20,28). (C) h(x) = 12 exactly three times in the open interval (20, 28). %3D (D) h has at least one discontinuity in the open interval (20, 28).
