618 000 in standard form​

5,600 x 10^3 = a) 560 b) 5,000,600 c) 5,600,000 d) 56,000

How do you determine if an ordered pair is a solution to a given equation?

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.
