Simplifying f(n) = 2f(n + -1) + 2 Multiply f * n fn = 2f(n + -1) + 2 Reorder the terms: fn = 2f(-1 + n) + 2 fn = (-1 * 2f + n * 2f) + 2 fn = (-2f + 2fn) + 2 Reorder the terms: fn = 2 + -2f + 2fn Solving fn = 2 + -2f + 2fn Solving for variable 'f'. Move all terms containing f to the left, all other terms to the right. Add '2f' to each side of the equation. 2f + fn = 2 + -2f + 2f + 2fn Combine like terms: -2f + 2f = 0 2f + fn = 2 + 0 + 2fn 2f + fn = 2 + 2fn Add '-2fn' to each side of the equation. 2f + fn + -2fn = 2 + 2fn + -2fn Combine like terms: fn + -2fn = -1fn 2f + -1fn = 2 + 2fn + -2fn Combine like terms: 2fn + -2fn = 0 2f + -1fn = 2 + 0 2f + -1fn = 2 Reorder the terms: -2 + 2f + -1fn = 2 + -2 Combine like terms: 2 + -2 = 0 -2 + 2f + -1fn = 0 The solution to this equation could not be determined.
