Answer 3

The domain of a function is all of the possible x-values, or in this case, m-values. Because it starts at time 0 and goes on forever after that, as no end point was specified, then the minimum m can be is 0 and there is no maximum because, as I said, it goes on forever.
Hence, \[0\le m.\]
