## Reflection: Writing Across the Disciplines Power to the Mathematician - Section 3: Wrap It Up

These examples of student "texts" show the different thinking of some of my students. Student A seems to have a pretty solid understanding not only of exponential functions but of appropriate mathematical writing.  Student B is less clear about exponential functions and definitely needs to work on her mathematical writing.  What's interesting is that both students understand the basic form of an exponential function including end behavior.
