(a) Using a graphing utility, draw a scatter plot of the data with time after diagnosis as the independent variable.
(b) Using a graphing utility, build an exponential model from the data.
(c) Express the function found in part (b) in the form A(t) = A0ekt .
(d) Graph the exponential function found in part (b) or (c) on the scatter plot.
(e) Use the model to predict the percentage of patients diagnosed with advanced-stage cancer who survive for 4 years after initial diagnosis.
