Let f be a twice-differentiable function such that f quot;(x) gt; 0 for all x. The graph of y = S(x) is the secant line passing through the points (3, f(3)) and (5, f(5)). The graph of y = T(x) is the line tangent to the graph of f at x = 4. Which of the following is true? (A) f(4.2) lt; S(4.2) (B) f(4.2) lt; T(4.2) lt; S(4.2) (C) T(4.2) lt; f(4.2) lt; S(4.2) (D) T(4.2) lt; f(4.2) lt; S(4.2)
