Best ResponseYou've already chosen the best response.0Awesome, thank you. Mind making sure I'm correct on another one? I think I know how to do them, I'm just checking..

Best ResponseYou've already chosen the best response.0Thank you... The cost in dollars of producing x units of a particular brand of notebook is C(x) = x2 – 400. Find the average rate of change of C with respect to x when the production level is changed from x = 100 to x = 102. 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.

Best ResponseYou've already chosen the best response.0So for A, you plug 102 in, and the 100. Subtract (c(102)  c(100)) then divide by 102100
