Police know the exact distance that it takes a car to stop at 80, 100, and 120 miles per hour. However at a crash scene, the police find skid marks longer than those left at any known speed. They use a graph to predict the car's speed as approximately 137 miles per hour. Predicting a value or quantity beyond a known data range, based on a trend in the data, is
A) deduction.
B) extrapolation.
C) interpolation.
D) observation.
