I used GeoGebra to find the answer. I entered the data into the spreadsheet portion, then created a list of points based off it. Lastly I applied the fitPoly function to that list to determine the regression model. https://wiki.geogebra.org/en/FitPoly_Command
It is possible to find the quadratic regression equation by hand, but it would be very tedious and take a while. It's recommended to use a specialized calculator instead.
