The radiator in a car filled with a solution of 70 per cent antifreeze and 30 per cent water. The manufacturer of the antifreeze suggests that for summer driving, optimal cooling of the engine is obtained with only 50 per cent antifreeze. If the capacity of the radiator is 4.9 liters. how much coolant (in liters) must be drained and replaced with pure water to reduce the antifreeze concentration to 50 per cent?​

What are the domain and range of the function? f(x) = -4 (sqrt)x
