Right in equation that will model the proportional relationship given in each real world situation. jennifer is shopping with her mother. they pay two dollars per round for tomatoes at the vegetable stand. find the constant of proportionality in the situation. right in equation to re-present the relationship.

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.
