Explanation:
Look, I don't remember this lesson. It was along ago since I got it. But I can choose the correct answer by logic.
If we will substitute in this equation when n = 0
gn = 12 x 3^n-1
g0 = 12 x 3^0-1
g0 = 12 ÷ 3 = 4 ###
So if we'll substituted in all the four answers when
n = 0
a. f(0) = 1/3 x 4^0 = 1/3
b. f(0) = 1/4 x 3^0 = 1/4
c. f(0) = 4 x 3^0 = 4 ###
d f(0) = 36 x 3^0 = 36
C. Is the correct answer
