A company had 39 employees when it was founded. The table shows the number of employees in the company and the corresponding number of years after it was founded. An analyst of the company used a graphing utility to construct the exponential regression to appropriately model the relationship between the number of years after the company was founded and the number of employees in the company. Which of the following exponential functions could be the model that the analyst constructed, where t is the number of years after the company was founded?

A. f(t)=1.28(39)t
B. f(t)=1.48(40)t
C. f(t)=39(1.28)t
D. f(t)=40(1.48)t
