Simplifying f(x) + f(-1x) = 2f(x) Multiply f * x fx + f(-1x) = 2f(x) Remove parenthesis around (-1x) fx + f * -1x = 2f(x) Reorder the terms for easier multiplication: fx + -1f * x = 2f(x) Multiply f * x fx + -1fx = 2f(x) Combine like terms: fx + -1fx = 0 0 = 2f(x) Multiply f * x 0 = 2fx Solving 0 = 2fx Solving for variable 'f'. Move all terms containing f to the left, all other terms to the right. Add '-2fx' to each side of the equation. 0 + -2fx = 2fx + -2fx Remove the zero: -2fx = 2fx + -2fx Combine like terms: 2fx + -2fx = 0 -2fx = 0 Divide each side by '-2'. fx = 0 Simplifying fx = 0 The solution to this equation could not be determined.
