According to the fundamental theorem of algebra, a polynomial function f(x) of degree n has exactly n roots, or zeros, as long as you allow for complex numbers and multiplicity." what does this say about x = 2 as the only apparent solution to x2 + 4x + 4 = 0?

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
