𝟏𝟏𝟏𝟏

𝟏𝟏𝟏𝟏

𝒇𝒇 � � = �𝟒𝟒 � � + 𝟑𝟑 = √𝟏𝟏𝟏𝟏 + 𝟑𝟑 = √𝟏𝟏𝟏𝟏 = 𝟒𝟒

𝟒𝟒

𝟒𝟒

𝒇𝒇(𝟗𝟗) = �𝟒𝟒(𝟗𝟗) + 𝟑𝟑 = √𝟑𝟑𝟑𝟑 + 𝟑𝟑 = √𝟑𝟑𝟑𝟑

𝟏𝟏

𝟏𝟏

𝒇𝒇 �− � = �𝟒𝟒 �− � + 𝟑𝟑 = √−𝟐𝟐 + 𝟑𝟑 = √𝟏𝟏 = 𝟏𝟏

Solution:

Let the fixed amount that the car rental charge be C and the amount charged per of mile be d

We can write the car rentals cost function as:

𝑓𝑓(𝑥𝑥) = 𝐶𝐶 + 𝑑𝑑 ∙ 𝑥𝑥

Where x is the distance in miles and f(x) is the total cost in dollars

Heidi rented a car and paid $100 for 200 miles, putting this in the cost function, we have

𝟏𝟏𝟏𝟏𝟏𝟏 = 𝑪𝑪 + 𝟐𝟐𝟐𝟐𝟐𝟐𝟐𝟐

Also on another day, Heidi paid $152.50 for 350 miles, putting this into the cost function,
