3 Select ALL the correct answers.
Consider the geometric sequence below.
-4, -6, -9, -3, -1
Select all functions that define the given sequence.
o f(n) = 4:(-" - 1)
f(1) = 4
s(n) = -3./(n − 1), for n = 2, 3, 4, ...
|(1) = -4
f(n) = 1. ((n 1), for n = 2, 3, 4, ...
r(n) = -4. ()" - 1)
O f(n) = -4.(-3) -1
O
f(1) = -4
(n) = -1. 1(n − 1), for n = 2, 3, 4, ...
