Typically desmos will calculate regression of nonlinear type functions if you write it in a "linear form" such as:
y1 ~ a(1/(x1 - h)2) + k
I used this and it gave me a regression (solved for the values of a, h and k) giving me an r2 value of 0.9732, so not too bad. Give it a try.
I'm not sure if that's the sort of thing you are being taught or not but it's OK. I think a log regression would give better results but that's not the question.

I did not provide the answer. To find the answer, you’ll need to use desmos. You can type in the equation that I listed above and desmos will calculate the values of a, h, and k. Then you can plug them in and you’ll have the the rational model they are asking for. The value of r^2 is just a measure of how good the model is.

so is the answer 0.9732, or is there a step you would like me to do find the answer as predicting the behavior as x increases beyond 209/01/21
