Hello,

I am trying to find the equations on my calculator for the price-demand and price supply equations. The data is in the attached image.

I think I am doing something wrong, but not sure what.

I found the quadratic regression model for the first set of data using my calculator, but I used the p=D(x) as list one, and x, as list two. I came up with

0.028x^2-23x +5743

is this right? or do I need the reverse the order?

For the price-supply data I but the p=S(x) as list 1 and x as list 2 and I got the linear regression function:

2 5.1x+342

Can you please let me know if I am on the right track?
