Jill's mom bought a generator to keep her appliances running during power outages. The generator is filled with 6.6 gallons of gasoline and consumes an average of 0.75 gallons of gasoline per hour. You can use a function to describe the amount of gasoline remaining in the generator after it runs for x hours. Write an equation for the function. If it is linear, write it in the form h(x) = mx + b. If it is exponential, write it in the form h(x) = a(b). please help
