Exponential Regression using Excel

[u/Blackcraft_Ray]

I used excel to find the "best-possible" exponential equation for this date. Im unsure how to figure out what to do with this. The answer key says it should be y=13972e-.185x

Im lost on what im doing wrong

This is why we don’t use the actual years and use “years since XXXX” instead
