Find the derivative of the function using the definition of derivative. g(u) = u +1 6u - 1 g'(u) = State the domain of the function. (Enter your answer using interval notation.) State the domain of its derivative. (Enter your answer using interval notation.) 24. [-/1 Points] DETAILS SCALCET9 2.8.065. MY NOTES ASK YOUR TEACHER The left-hand and right-hand derivatives of f at a are defined by f'_(a) = lim f(a + h) - f(a) and f' (a) = lim f(a + h) - f(a) h-0 h hot h if these limits exist. Then f'(a) exists if and only if these one-sided derivatives exist and are equal. Let if x 5 0 f ( x ) = 16 - X if 0
