I'm assuming the 3.4's units are gallons, too. If you're rounding to the nearest <em>whole gallon</em>, that means you're going to have round 3.4 to the nearest <em>whole number. </em>Think about the two whole numbers 3.4 lies between: 3 and 4. Which one of those is 3.4 closer to? That's where you'll want to round.

A definitely has to be one because it's a fact and you need to know what it looks like. B isn't true because the greatest integer function rounds down values. C is also not correct because a one-to-one graph has one x-value for every y-value. This one doesn't. D has to be true because f[0] = 0 because the Greatest Integer Function requires it to be. And E is also correct because that's in the definition of a Greatest Integer Function. So, your answers are A, D and E.
