Modeling From Tables
It is also possible to look at the table, without the graph, to find the best model. When doing this, use what was taught in previous lessons about common differences and ratios.
For a linear function, the table will show a common first difference. For a quadratic function, the table will show a common second difference. For a cubic function, the table will show a common third difference. For an exponential function, the table will show a common ratio.
