1. Objective: To model functions using rules, tables and graphs

3.  x(x, y) -4 0 2

4. B) Model the function rule f(x) = 3x + 4 using a table of values and a graph. xf(x) = 3x + 4(x, y) 0 1

5. A)Suppose your group recorded a CD. Now you want to copy and sell it. One Company charges $250 for making a master CD and designing the art for the cover. There is also a cost of $3 to burn each CD. The total cost P(c) depends on the number of CDs (c) burned. c P(c)= 3c + 250 (c, P(c) ) 100 200 300 500

6. B)At the local video store you can rent a video game for $3. It costs you $5 a month to operate your video game player. The total monthly cost C(v) depends on the number of video games “v” you rent. v C(v)= 3v + 5 (v, C(v) )
