Answer
Fill the blanks with:
antiderivative, marginal
Work Step by Step
See section 11-2, Marginal Analysis.
The marginal cost function $C'(x)$ is the derivative of the cost function $C(x)$.
In this section we defined $F(x)$ is an antiderivative of $f(x)$ if
$\quad F'(x)=f(x)$,
So, $C(x)$ (cost function) is an antiderivative of $C'(x)$ (marginal cost function).
