    Sometimes the graphing will only be an approximation of an answer (or it will round when it shouldn't), while solving algebraically will sometimes give you an exact answer. For example the graph y=1/x is never supposed to touch y=0; however, if you use a graphing calculator and make the window size big enough you will see that it will eventually say y=0 as you trace the graph along.
