If U(x – 2) = 20, find the value of x. 9. Suppose y(K, L) = K 2 L. a. Find the partial derivative of y w.r.t K and L (that is, ∂ y/ ∂ K =? and ∂ y/ ∂ L = ?). b. Is ∂ y/ ∂ K increasing or decreasing in K? c. What can you say about the relationship between ∂ y/ ∂ L and L? d. Draw the graphs of ∂ y/ ∂ K vs. K with L fixed at 10. e. Draw the graphs of ∂ y/ ∂ L vs. L with K= 5....
