How to create a quadratic model using Desmos?

We can use desmos to create a quadratic model that fits the given data. On desmos, type the data into a table with the x-values in the first column and the y-values in the second column. Then, to tell desmos to compute a quadratic model, type in y 1 ~ a x 12 + b x 1 + c. You will get a result that looks like this:

Is there a way to get the equation of a line using Desmo?

I know you can find the line by putting in g (x)=d/dx f (x) for example. But is there a way to get the equation of that line using desmos? Can I also do this for anti derivatives? You can graph anti-derivative like this, but Desmos cannot give the equations for these. If you're looking for software that does do this, you can use Mathematica.
