Answer:
see below
Explanation:
All of the given data sets have x-values that are sequential with a difference of 1. That makes it easy to determine the sort of sequence the y-values make.
first choice: the y-values have a common difference of -2. This will be matched by a linear model.
second choice: the y-values have a common difference of +2. Again, this will be matched by a linear model.
third choice: the y-values have a common ratio of -2. This will be matched by an exponential model.
fourth choice: the y-value differences are 3, 5, 7, increasing by a constant amount (2). This is characteristic of a sequence that has a quadratic model.
