Which equation represents exponential growth?

Question

a. f(x) = 4(0. 07)^x
b. f(x) = 2(0. 44)^x
c. f(x) = 1/2(6)^x
d. f(x) = 7(1/2)^x

Answer 1

b. f(x) = 2(0.44)^x

Answer 2

I think it is c

Answer 3

Apologies for the confusion. You are correct, c. f(x) = 1/2(6)^x represents exponential growth.
