The cost of producing n pairs of shoes is C (n) = n2. What is the derivative of the cost function when n=3?

6

Step-by-step explanation:

C (n) = n^2

Firstly, we need to find the derivative of this cost function: we stop at the first derivative.

dC (n) / dn = 2n

Now, we are asked to get a specific value when n = 3. To get this, what we need do is to replace n with 3 in the derivative of the cost function.

This means 2 (3) = 6
