Four brands of tires (A, B, C, D) are to be compared for tread wear after 24,000 miles of driving. An experiment was executed by installing four tires of each brand in four cars randomly and the following tread wears were measured in millimeters after 24,000 miles driving of each cars. Determine if there is any significant difference between four tire brands.

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.
