What 2 pieces of mathematical information do a table, a graph, and an equation have in common?

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.

Of course you, with some mathematical knowledge, also can notice those things when you have the equation, so this is a thing that the 3 have in common.

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.
