The cost in dollars of producing x units of a particular telephone is c(x) = x2 – 2500. find the average rate of change of c with respect to x when the production level is changed from x = 100 to x = 103. include units in your answer. find the instantaneous rate of change of c with respect to x when x = 100. include units in your answer.
Answers: 1
![m = \dfrac{f(b)-f(a)}{b-a} = \dfrac{f(103)-f(100)}{103-100}\\\\ = \dfrac{(103)^2-2500-[(100)^2-2500]}{103-100} = \dfrac{609}{3}=203](/tpl/images/0137/1211/99069.png)
