  2. What’s the Deal? • Raven’s Cupcake Company ships cupcakes all over the country. There is a flat rate of $2.00 for every order shipped, and cupcakes cost $6.00 a dozen. What is the total cost if Shantaniatia orders three dozen cupcakes?

  3. X and Y? • Your ‘x’ value is the number of cupcakes that she purchases, which we already determined was three. So x=3. • Your ‘y’ value is the total amount that the order will cost, which will be determined in a later slide. • Equation: y=$2.00+6x

  4. Independent and Dependent? • Our independent value is….the number of dozens of cupcakes purchased • Our dependent value….is the total cost of the cupcake plus shipping • So, the total amount required to purchase the cupcakes depends on the number of cupcakes purchased!

  5. Function? • In case you were wondering, yes, this is a function because it has independent and dependent values!!

  6. Domain and Range! • The domain is all of the possible x values. Lets just use… D:{1,2,3,4,5,6,7} The range is all the possible y values. To determine the y values, we have to use our formula, which is y=$2.00+6x… R:{$8, 14, 20, 26, 32, 38, 44}

  7. Continuous or Discrete? • This domain is continuous, because you can get any number of cupcakes.

  8. Function Notation If this equation were written in function notation, it would look like this… f(x)=$2.00+6x

  9. Equation Stated • If we were to write this equation in what I like to call standard notation it would look like…. y= $2.00+6x

  10. Possible Outcomes • Some of the possible outcomes to this equation are as follows…

  11. Graph • This is what some of the outcomes would look like on a graph… Total Cost Number of Cupcakes

  12. So… • Now that we know how to find our answer, we should be able to figure out that Shantaniatia will have to pay $20.00 for her cupcakes and their shipping. We also hopefully learned a little more about functions from Raven Morris!
