: Let k(x) = f(x) + g(x). The derivative of a difference is the difference of the derivatives: Proof: Let k(x) = f(x) - g(x). The derivative of the product of a function and a constant is the product of the constant and the derivative of the function: Proof: Let k(x) = cf(x). Higher order derivatives: (derivative of a derivative): ................
