Consider the production function
Q = 4K ^ (3/4) * L ^ (1/4)
a. Find the gradient of Q
b. Find the Hessian of Q
c. Denote the initial K = 10,000 and L = 625. Consider an increase of K by ?K and similarly an increase of L by ?L. Find the Taylor approximation for this function. f(x + ?x) = f(x) + ?x^(T) * ∇f(x) + (1/2)?x^(T) * H(x)?x + o(k ?x k2)
