Trends:
In the graph or a table you easily can see trends in the data, for example, parts where if x increases also does y, or things like that.

Range:
You usually can see the whole range (all the possible y values) of your equation by looking at the graph or the data set. And obviously, if you have the equation you can easily find the range of it.
