The number of camera phones shipped globally can be modeled by the function y=1.28e^1.31x where x is the number of years since 1997 and years since 1997 and y is the number of camera phones shipped in millions. how many camera phones were shipped in 2014

The equation represents the function f, and the graph represents the function g. f(x)=3(5/2)^x determine the relationship between the growth factors of f and g. a. the growth factor of g is twice the growth factor of f. b. the growth factor of f is twice the growth factor of g. c. the growth factor of f is 2.5 times the growth factor of g. d. the growth factor of f is the same as the growth factor of g.
