Linear, Exponential, and Quadratic Models
Key Questions

I will be assuming you are using a TI83 or a TI84, as those are the most common. The entire process is quite long and elaborate, so I strongly suggest you use this pdf.
Even if I tried to type everything up here, it would be quite long and confusing, as well as redundant.
