m must be a negative integer. Technically from the way that my professor phrased it, shouldn't m be -infinity?

"... shouldn't m be -infinity?"
2^(-infinity) = 0, and 1+0 is not greater than 1. So, no, the way the professor phrased it, -infinity is not the answer.
Do as the professor instructed and write some code with a while loop to figure out the answer.

Precision differs in MATLAB and theoretical calculation. So when you write while loop you will know the difference.
