The money values of some objects, determined by me, are written in the table below. Using regression, we can predict the values of items according to the level where they start to be used. The formula is $$y = -0.00136x^2 + 0.0094x + 2.09$$, where $$ y $$ is the value of the item and $$x$$ is the level when the item starts to be used. I used a 3rd-degree curve because its goes through the point of origin, unlike the 2nd-degree curve that passes through $$(5.307, 0)$$.

The values for lower resources can be predicted.
