Answer:
d: the domain of C would be [0, ∞]
e: The slope represents the cost per mile of renting the truck
f: The y-intercept is the point (0, 40). That would be the minimum cost of renting the truck
Step-by-step explanation:
d: The domain is all values x CAN be. In this problem, x represents the number of miles you are renting the truck for. You can't have negative distance, so the least amount miles you could rent the truck for is 0 miles. The most amount of miles you could rent to truck for in a day is an infinite amount of miles. That's not really possible, but theoretically possible, so it's the upper limit of our domain.
e: The 0.25 represents the cost per mile, so 0.25x will give you the cost based on how ever miles you drive
f: The y-intercept is at (0, 40) because $40 is the least cost you could spend on renting the truck because the problem tells us that there is a flat cost of $40 just for renting the truck.
