Can i get some ? i thought the answer to x was 35 but im not sure (image)

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

Which statement best describes how to determine whether f(x) = x squared- x +8 is an even function ?

I'm marking the brainliest and it's 15 points
