2. Intro to Derivatives

A firm’s total cost (in dollars) to produce $q$ units is $C\left(q\right)=500+20q+0.5q^2$. What is the marginal cost function $MC\left(q\right)$?

In business calculus, if $R\left(x\right)$ is the total revenue from selling $x$ units, what is the best definition of marginal revenue?

In business calculus, marginal cost is best defined as the change in which quantity with respect to output quantity $q$?

In business calculus, which definition best describes marginal cost?

In economics, marginal cost is defined as the derivative of total cost with respect to quantity produced. If total cost is $C\left(q\right)$, which expression represents marginal cost?

In business calculus, marginal cost is defined as which of the following?

In business calculus, if $C\left(x\right)$ is the total cost to produce $x$ units, what is the marginal cost at output level $x$?

In business calculus, if total cost is given by $C\left(x\right)$ where $x$ is the number of units produced, what does marginal cost refer to?

In business calculus, marginal cost is interpreted as a derivative. What does marginal cost refer to?
