Step-by-step explanation:
Explicit formula of a G.P. is given by,
Here, = nth term
a = First term
n = number of term
r = common ratio
Given sequence is 3, 6, 12, .......
a = 3
r = = 2
Therefore, explicit formula will be,
Option (3) is the answer.
Parent function → f(x) = 3ˣ
Transformed function → g(x) =
Since, g(x) = f(x + 5)
Therefore, function 'f' has been shifted 5 units left.
Option (1) is the answer.
