For the problem below, I was asked to list the vertical shrink or stretch of the function below.

Also, below I created a table of X and Y values. I need help understanding how to determine what value the vertical "shrink" or "stretch" is. Thanks!

Problem:

g(x) = 1/6x²

Table

X Y

-2 0.667

-1 0.167

0 0

1 0.167

2 0.667
