Question

Karl set out to Alaska on his truckThe amount of fuel remaining in the truck's tank (in liters) as a function of distance driven (in kilometers) isgraphed500450400-350300-Fuel (liters)250-200+150-10050100200700800300 400 500 600Distance (kilometers)What distance did Karl travel by the time he had 200 liters of fuel?

Answer 1

Search for the value of the function when the fuel has a value of 200 L.

Drawing a horizontal line at the value of 200L, we can see that the function intercepts the horizontal line when the x-value is equal to 500 km.

Therefore, by the time Karl had 200 liters of fuel, he had traveled 500 km.
