Question

Sarah's car has a maximum capacity of 15 gallons of gas. The function f (g) = 3.50g models the relationship between the total cost of gasoline, f (g), and the number of gallons of gasoline purchased, g. What is the most appropriate domain of the function?

Answer 1

Anaman, this is the solution:

As you can read, Sarah's car has a gas capacity between 0 and a maximum of 15 gallons.

Therefore, the domain of this function should be the set of numbers between 0 and 15.

The correct answer is A.

0 (less than and equal to) g (less than and equal to) 15
