The daily total cost C(x) incurred by Trappee and Sons for producing x cases of TexaPep hot sauce is given by the following function. C(x) = 0.000002x3 + 9x + 300 Calculate the following for h = 1, 0.1, 0.01, 0.001, and 0.0001. (Round your answers to four decimal places.) C(100 + h) − C(100) / h

h = 1 h = 0.1 h = 0.01 h = 0.001 h = 0.0001

Use your results to estimate the rate of change of the total cost function when the level of production is 100 cases/day. (Round your answer to two decimal places.)
