2. My Real World Problem Sam bought 5 pairs of sunglasses. How much money should she expect to pay if each pair is $9.99?

3. The Equation My equation: y=9.99x OR f(x)=9.99x y is the price of the sunglasses. x is the number of pairs of sunglasses.

4. Independent and Dependent Variables The independent variable is y. The dependent variable is x. Y depends on X.

5. Is this a Function? Yes, this is a function, because all x’s are different.

6. Domain and Range Domain- x values. Range- y values.

7. Domain D:{ 1,2,3,4,5} (x values)

8. Range R:{10,20,30,40,50} (y values)

9. Continuous or Discrete? Discrete, because the x values are limited.

10. x f(x)=10x y(x,y) 1F(1)=10(1)101,10 2F(2)=10(2)202,20 3F(3)=10(3)303,30 4F(4)=10(4)404,40 5F(5)=10(5)505,50 Equation: f(x)=10x Function Notation: f(x)=10x
