𝐅𝐑𝐐 𝟐 The function 𝑓 is twice differentiable for all values of 𝑥. A portion of the graph of 𝑓 is shown above along with the line tangent to the graph of 𝑓 at 𝑥 = 12. The graph of 𝑓 has horizontal tangent lines at 𝑥 = 3, 𝑥 = 6, and 𝑥 = 10. The region R is bounded by the graph of 𝑓 and the 𝑥-axis and has area 22. 12
