For this case we have a function of the form:
 y = A * (b) ^ x
 Where,
 A: initial amount
 b: growth rate
 x: domain of the function.
 We have then that the function is:
 y = 2 * (3) ^ x
 For example,
 for x = 0:
 y = 2 * (3) ^ 0
 y = 2
 for x = 1:
 y = 2 * (3) ^ 1
 y = 6
 for x = 2:
 y = 2 * (3) ^ 2
 y = 18
 for x = 3:
 y = 2 * (3) ^ 3
 y = 54
 Answer:
 
y = 2 * (3) ^ x
