Simplifying f(x) = (3 + -2x + -3x) * 4 Multiply f * x fx = (3 + -2x + -3x) * 4 Combine like terms: -2x + -3x = -5x fx = (3 + -5x) * 4 Reorder the terms for easier multiplication: fx = 4(3 + -5x) fx = (3 * 4 + -5x * 4) fx = (12 + -20x) Solving fx = 12 + -20x Solving for variable 'f'. Move all terms containing f to the left, all other terms to the right. Divide each side by 'x'. f = 12x-1 + -20 Simplifying f = 12x-1 + -20 Reorder the terms: f = -20 + 12x-1
