27. The graph of a twice differentiable function \( f \) is shown in the figure above. Which of the following is true?






Answer is: option3

\( f'(2) < f(2) < f''(2) \)

Solution:

  1. The function is decreasing at \( x = 2 \Rightarrow \) so the slope \( f'(2) < 0 \)
  2. The curve is concave up at \( x = 2 \Rightarrow \) meaning the graph is curving upward, so: \( f''(2) > 0 \)

Given \( f(2) = 0 \), we now have:

  1. \( f'(2) < 0 \)
  2. \( f(2) = 0 \)
  3. \( f''(2) > 0 \)

From least to greatest:

\( f'(2) < f(2) < f''(2) \)

Correct Answer: \( f'(2) < f(2) < f''(2) \)
