Which set of ordered pairs represents y as a function of x?

Question 1 options:

{(1, 2), (2, 3), (3, 4), (3, 5)}

{(1, 3), (1, 5), (1, 7), (1, 9), (1, 11)}

{(2, 3), (3, 5), (3, -5), (-2, 8), (-2, -8)

{(1, 2), (2, -3), (3, 4), (4, -5)}

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.
