Handouts: What's the Difference?
                 Revenue, Cost, Profit
                 Slopes and Linear Functions

Today's objectives:
 1. Perform a break-even analysis:
     a. Use the graph or formula of Revenue, Cost, or Profit to determine the break-even quantity (or quantities).
     b. Determine the amount of Revenue or Cost at a break-even quantity.
2. Use graphs to determine the production level when a company will maximize Revenue or maximize Profit.
3. Interpret the slope and y-intercept of a linear function if it represents Cost, Revenue, or Profit.

Due Friday, January 17

Handouts:  Slopes and Linear Functions
                 Supply and Demand

Today's objectives:
1. Find and interpret the slope and axis intercepts of a linear demand function.
2. Find the formula of a cost function without given the y-intercept.
3. Find marginal cost, marginal revenue, and marginal profit from a formula or graph.
4. Determine the equilibrium quantity if given the formulas or graphs of the supply and demand.
    At a given price find if the market has a consumer surplus (like this) or shortage (like this) and how it affects the price.

Due Wednesday, January 22

Quadratic Functions (2.1 & 2.2)
 

Handout:  Revenue Rectangles

Today's objectives:
1. Use the table feature and intersection finder of a grapher to solve problems involving supply and demand functions.
2. Given the formulas of a linear cost function C(x) = mx + b and a quadratic revenue function R(x),
     find any break-even quantities and create the profit function. Use the intersection feature of a grapher to help you.
3. Given the formula of a quadratic function find any zeros and its vertex.
4. Given a linear price-demand function p(x), create the revenue function R(x) = x·p(x) and maximize the revenue.
    Use the intercepts of the demand line to help you.
    Similarly if you have a demand price function q = D(p) find R(p) = p·q. =  p·D(p).
