Consider the following. f(h, k) = (32:13 + 15!:2 - 10h + 47) - (43k + 15) when h = 4.2, k = 3.7, and N: = 0.3 (a) Calculate the output associated with the given input values. (Round your answer to three decimal places.) 4.2, 3.7) = 459696.426 (b) Approximate the change needed in one input variable to compensate for the given change in the other input variable. (Round your answer to three decimal places.) m=-x
