1. Blue Day – 1/8/2014 Gold Day – 1/9/2014

2.  Finish domain and Range worksheet from last class.

3.  Study of functions  Independent vs. Dependent  Last day to do a schedule change is Friday, January 16, 2015.  Student Holiday – Monday, January 19, 2015

4. In an Algebraic situation, equation, table, or graph, the variables (usually x and y) can be classified as either __________ or _________. independent dependent

5. The independent variable is always located on the _________ of a graph. The independent variable is the ________________. It is usually the ________ in a table or equation. The independent variable STANDS ALONE (___________). The independent variable is what happens _______. x-axis Input (domain) “x” Does not depend FIRST

6. The variable in a function whose value is subject to choice is the independent variable. The independent variable affects the value of the dependent variable.

7. The dependent variable is always located on the _________ of a graph. The dependent variable is the ______________. It is usually the _______ in a table or equation. The dependent variable DEPENDS on the ________________. The dependent variable is what happens _______. y-axis Output (Range) “y” independent variable 2nd

8. The variable in a function whose value is determined by the independent variable is the dependent variable.

9. Changing the independent variable Causes changes in the Dependent variable! The dependent variable depends on the independent variable!!! X Y

10. 1. A student’s grade depends on how much she studies. Independent variable:__________ Dependent variable:___________ 2. The height of a plant and the amount you water it. Independent variable: ___________ Dependent variable: _____________ Time studying grade Amount watered height

11. 3. The amount of money you make and the number of hours you work. Independent variable: _____________ Dependent variable:_____________ 4. The number of sodas you buy and the total money spent. Independent variable:______________ Dependent variable:_______________ 5. The number of houses you can paint depends on how much time you have. Independent variable:______________ Dependent variable:_______________ Hours worked Amount of money Number of sodas Total money Amount of time Number of houses

12. Data that is continuous is data that _________ happens. You can usually tell that your data is continuous if you are _________ something (i.e. time, distance, length, height, etc.). If your data is continuous, then you will _________ the points on your graph. continuously measuring connect

13. You can tell that your data is discrete if you are ________________________ (i.e. number of people, cars, or stories of a building). If your data is discrete, then you will _____________ the points on your graph. counting or measuring in whole numbers NOT connect
