Scientists are conducting an experiment with a gas in a sealed container. The mass of the gas is measured, and the scientists realize that the gas is leaking at a constant rate of 9 grams per minute. Ten minutes after the experiment started, the gas in the container has a mass of 342 grams. Let be the number of minutes that have passed since the experiment started, and let f(x) be the mass of the gas, in grams, at that moment. a. Write an equation for f f(x) = b. 33 minutes after the experiment started, there would be c. If a linear model continues to be accurate, started, all gas in the container will be gone. grams of gas left. minutes since the experiment
