Understanding Variables in a Cost Function

The video tutorial explains the cost function C of M, which calculates the cost to rent a car based on miles driven. It identifies the independent variable (M, in miles) and the dependent variable (C, in dollars). The tutorial also discusses the use of function notation and emphasizes the relationship between the number of miles driven and the cost.

What does the function C of M represent in the context of renting a car?

• The average speed of the car

• The cost of renting a car based on miles driven

• The total number of cars rented

• The number of days a car is rented

In the cost function, what is the independent variable?

• The cost in dollars

• The number of miles driven

• The number of days rented

• The type of car rented

What are the units of the dependent variable in the cost function?

• Miles

• Kilometers

• Dollars

• Days

How can the dependent variable be represented in function notation?

• M of D

• C of M

• D of M

• M of C

Why is the cost considered the dependent variable in this function?

• Because it depends on the number of miles driven

• Because it is measured in miles

• Because it is always constant

• Because it is the input variable
