It takes an older pump 4 times as long to drain a certain pool as it does a newer pump. working together, it takes the two pumps 4 hours to drain the pool. how long will it take the older pump to drain the pool working alone?

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.
