[NEED HELP FAST] A poster is shown below:

(The poster is a rectangle with a height of 6in and a length of 18 in)

What are the dimensions if the poster is enlarged by a factor of 7/2?

A. 42in by 126in

B. 3in by 9in

C. 9in by 12in

D. 21in by 63in

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.
