When solving a system by substitution, one should
a. look for coefficients that are reciprocals
b. solve for x or y in one equation first
c. look for coefficients that are the same or opposites
d. always multiply by -1

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.
