A collector's coin originally purchased for $3 in 1994 is expected to double in value by the year 2004. Write the equation of an exponential function to model this situation.Explain your answer.
----------------------
11 years from 1994 to 2004.
------------------------
EQUATION:
A(t)=A(0)2^(t/11)
A(t) = 3*2^(t/11)
