2. Real world problem  Josh got $155.75 for his birthday, and he bought x pair of shoes with it.

3. Equation  Y= 155.75-25x

4. Independent and dependent variables  The change depends on the amount of money spent.

5. Is it a function? Why?  Yes, because it passes the vertical line test, and the x value doesn’t repeat.

6. Definition for domain and range.  Domain- the set of possible input values of a relation or function. ( 1,2,3,4,5)  Range- the set of output values of a function or relation. ( 130.75, 105.75, 80.75, 55.75, 30.75)

7. Is the domain continuous or discrete? Why?  Discrete, because you cant buy a half a pair of shoes.

8. Equation stated and function notation  Y= 155.75-25x  F(x)= 155.75-25x
