If your car gets 20 miles to the gallon and you have 10 gallons of gas in your car how many miles will your car drive before it runs out of gas?

Equation  Y=x(20)

Independent and Dependent Variables  Y= How many miles you go.  X= How many gallons in the tank.

Independent and Dependent Statement  The number of miles driven depends on the amount of gallons of gas in your car.

Independent Variable  Independent is the amount of gas in the car.

Dependent  Dependent is the number of miles driven.

Is this a function?  Yes, this is a function because the amount of gas determines how far your car can drive.

Domain  Domain is the x value.

Range  Range is the y value.

Is the domain continuous or discrete?  The domain is continuous because there are no fixed x cordinates.

Equation Stated  Y=x(20)

Function Notation  F(x)=x(20)
