Simplifying f(n) = -2(n + -1) + 1 Multiply f * n fn = -2(n + -1) + 1 Reorder the terms: fn = -2(-1 + n) + 1 fn = (-1 * -2 + n * -2) + 1 fn = (2 + -2n) + 1 Reorder the terms: fn = 2 + 1 + -2n Combine like terms: 2 + 1 = 3 fn = 3 + -2n Solving fn = 3 + -2n Solving for variable 'f'. Move all terms containing f to the left, all other terms to the right. Divide each side by 'n'. f = 3n-1 + -2 Simplifying f = 3n-1 + -2 Reorder the terms: f = -2 + 3n-1
