Simplifying f(-1x) = 2x2 + 2x + 9 Remove parenthesis around (-1x) f * -1x = 2x2 + 2x + 9 Reorder the terms for easier multiplication: -1f * x = 2x2 + 2x + 9 Multiply f * x -1fx = 2x2 + 2x + 9 Reorder the terms: -1fx = 9 + 2x + 2x2 Solving -1fx = 9 + 2x + 2x2 Solving for variable 'f'. Move all terms containing f to the left, all other terms to the right. Divide each side by '-1x'. f = -9x-1 + -2 + -2x Simplifying f = -9x-1 + -2 + -2x Reorder the terms: f = -2 + -9x-1 + -2x
