Is it true that ƒ −(g − h) = (ƒ − g) − h? Explain why you believe the equation is true or provide a counterexample to show that it is not. A. Yes; the subtraction operation has the Commutative Property. B. Yes; the subtraction operation has the Associative Property. C. No; the subtraction operation does not have the Distributive Property. D. No; let ƒ(x) = x2, g(x) = x, and h(x) = 1. Then (ƒ − (g − h))(x) = x2 − x + 1 but ((ƒ − g) − h)(x) = x2 − x − 1.
