One type of plant root splits 4 times while growing in the ground. The number of new roots after each split can be modeled by the function f(x)=3^x, where x is the number of times the root splits.

What is the domain of f(x)?

Possible answers:

All positive integers

All positive integers less than or equal to 4

All integers

All positive integers greater than or equal to 4

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.
