Studies have shown that the number of accidents a driver has varies with the age of the driver, and is highest for very young and very old drivers. The number of serious accidents for drivers of age x during a recent year was approximately f(x) = 0.013x2 − 1.38x + 48 for 16 ≤ x ≤ 85. Find the age that has the least accidents, rounding your answer to the nearest year. x = years old
