Average Rate of Change
A company that makes wooden toys has determined that the cost of producing toys is given by the function C(x) =x^2 + 7. Find the average rate of change in cost for increasing production from x =1 units to x = 4 units.
I thought I knew how to do these but I consistently get this problem wrong. Where do I start with it?
Rate of change is defined by a derivative. In calculus, the average is defined by:
To sum, you need to find:
Ahhh okay. So the answer should be 5, correct?
That's what I calculated.
