The atmospheric pressure (in millibars) at a given altitude (in meters) is shown in the table.
(a) Use a graphing calculator to make a scatter diagram of the data for atmospheric pressure P at altitude x.
(b) Would a linear or an exponential function fit the data better?
(c) The following function approximates the data. P(x) = 1013e-0.0001341x
Use a graphing calculator to graph P and the data on the same coordinate axes.
(d) Use P to predict the pressures at 1500 m and 11,000 m, and compare them to the actual values of 846 millibars and 227 millibars, respectively.
