Help me please . Very much appreciated​

What is the logarithmic function modeled by the following table? x f(x) 9 2 27 3 81 4

What is always true about a positive integer raised to a negative odd power?

Someone answer this asap for the first five terms of a sequence are shown. 5, 11, 23, 47, 95, . . which recursive function defines the nth term in the sequence for n > 1? a. f(n) = f(n - 1) + 6 b) f(n) = f(n - 1) + 48 c) f(n) = 3 • f(n - 1) + 1 d) f(n) = 3 • f(n - 1) - 4
