The line tangent to the graph of the twice-differentiable function f at the point x=3 is used to approximate the value of f(3.25).

Which of the following statements guarantees that the tangent line approximation at x=3.25 is an underestimate of f(3.25)?


A. The function f is decreasing on the interval 3 ≤ x ≤ 3.25

B. The function f is increasing on the interval 3 ≤ x ≤ 3.25

C. The function f is concave down on the interval 3 ≤ x ≤ 3.25

D. The function f is concave up the interval 3 ≤ x ≤ 3.25
