Respuesta :

Answer:

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.
