- Good practice for students learning about computer output too, it's important to learn that not everything is hand-delivered in a nice equation; coefficients are often given in tables when technology does the work.
The only thing I think that could improve it is making the scatter plots have a less awkward window, or one that can be changed. Or at least include x=0 and/or y=0 when appropriate.

- I think it's useful but I was looking for an equation in exponential form, y=ab^x. After looking I realized that it doesn't put it in the equation form although it does put it in the table below where it says A and then a # for it and same with B. So they do give you the equation but you have to make it and it's a little hard to find and it would be very helpful if they put the equation out there.
