Table of Values & First difference to Analyze Quadratics.
How to figure out if the reation is linear or non-linear.
Example: Linear relation
Table of values shows you the relationship between time, in one month intervals, and the height of a plant. Is the relation linear or non-linear?
As you can see from this table of values that, the relation is linear because the first difference is constant.
Non-linear relation (quadratic)
The relation is quadratic since, the first difference isn't constant but the second difference is.
