Simplifying f(x) = 2x * 2 + 4x + -7 Multiply f * x fx = 2x * 2 + 4x + -7 Reorder the terms for easier multiplication: fx = 2 * 2x + 4x + -7 Multiply 2 * 2 fx = 4x + 4x + -7 Reorder the terms: fx = -7 + 4x + 4x Combine like terms: 4x + 4x = 8x fx = -7 + 8x Solving fx = -7 + 8x Solving for variable 'f'. Move all terms containing f to the left, all other terms to the right. Divide each side by 'x'. f = -7x-1 + 8 Simplifying f = -7x-1 + 8 Reorder the terms: f = 8 + -7x-1
