The change in the X values is in multiples of 2.
The change in the h(x) values need to be: -0.3 x 2 = -0.6
Now find the h(x) values that have a difference of -0.6
A negative value is a decrease.
2 to 4 is an increase.
4 to 6 is an increase.
6 to 8 is an increase.
8 to 10 is an increase.
10 to 12 = 20-19.8 = 0.2
12 to 14 = 19.8 - 19.2 = 0.6
The two columns are 12 and 14
