Solve the problem.Suppose that the speed of a car, measured in miles per hour (mph), is monitored for some short period of time after the driver applies the brakes. The following table relates the speed of the car to the amount of time, measured in seconds (sec), elapsed from the moment that the brakes are applied.
Represent the data in the table graphically with elapsed time on the horizontal axis and speed on the vertical axis. Would a linear function give an approximate fit?
What will be an ideal response?
A linear function does not give an approximate fit.
