Use the Theorem on Limits of Rational Functions to find the limit. If​ necessary, state that the limit does not exist.

  The equation is y = [x]

Using the given​ graph, at which x​-value is the derivative of this function​ undefined?

Use the graph of​ F to find the given limit. When​ necessary, state that the limit does not exist.     =

Cyber Manufacturing determines that the daily​ revenue, in​ dollars, from the sale of x laptops is ​R(x) = 0.005×3 + 0.03×2 + 0.8x. Find the marginal revenue for x​ =140 and explain what it means.

  A company estimates that the daily cost (in dollars) of producing x chocolate bars is given by .  Currently the company produces 650 chocolate bars per day. Use marginal cost to estimate the increase in the daily cost if one additional chocolate bar is produced per day.  $[x]

The price p​ (in dollars) and demand x for wireless headphones are related by

  The maximum profit is $[x].  To obtain the maximum​ profit, the price per suit must be $[y].
