Exercise 6 Page 143

How do the consecutive terms relate to each other?

Linear

Practice makes perfect
We want to identify which kind of model best describes the data: linear, quadratic or exponential. To do so we will calculate the difference between consecutive terms.
x -3 -2 -1 0
y -6.75 -7.5 -8.25 -9

Let's begin with calculating the first differences.

Since the first differences are all equal, the table of values represents a linear function.
