Ответ:
Option (D)
Step-by-step explanation:
Rate of emptying the fuel tank = 7.5 liters per minute
Fuel emptied in x minute = 7.5x liters
Volume of the fuel in the fuel tank initially = 175 liters
Therefore, amount of fuel left in the tank after x minutes = (175 - 7.5x) liters
Function representing the emptying of the fuel tank will be,
f(x) = 175 - 7.5x
Option (D) will be the answer.
