Cost function

The marginal cost for a product is MC=40 + x^2. Find the cost function if the cost for 6 units is $500.

I'm not sure exactly what to do with this one. I would think that you simply find the integral of MC to get the cost function, but the 6 units for 500 leads me to belive that's not so. What do i do?

Re: Cost function

We are essentially given the initial value problem:


Thus, we may write:
