REAL WORLD PROBLEM

Problem A rental company is $150 to rent a

car plus 10 cents a mile.

Equation y= .10x+150

INDEPENDENT AND DEPENDENT VARIABLES

Dependent: The total cost to rent a carIndependent: The number of miles

driven

Is this a Function?Yes

Why ?Because the X values repeat.

DOMAIN AND RANGE

Domain: the domain of a relation is the set of all coordinates from each pair x> 0

Range: The range of a relation is the set of all Y coordinates from each ordered pairs x> 150

Is Domain Continuous or Discrete?

It is continuous Why?It is continuous because you can drive any amount of miles.

THE EQUATION

Y=.10x+150
