<h2>Answer:</h2>

The marginal cost when x=8 is:

                          375

<h2>Step-by-step explanation:</h2>

We know that the marginal function for a cost function C(x) at x=a

is given by:

   C'(x) at x=a

Here we have the cost function C(x) as:

C(x)=110+7x-x^2+2x^3

Now we find the derivative of C(x) with respect to x.

i.e.

C'(x)=0+7-2x+6x^2

( Since,

\dfrac{d}{dx} x^n=nx^{n-1}  )

C'(x)=7-2x+6x^2

Hence, we get:

C'(8)=7-2\times 8+6\times (8)^2\\\\i.e.\\\\C'(8)=7-16+384\\\\C'(8)=375
