I'm using excel with the x and y values in chart attached. (12 sets)Linear model with equation y=5961.2x-1E+07Then I have to figure the quadratic. Per excel it came up with y=11.94x2 - 40725x + 3E+07**how well does the quadratic model fit the data. Is it a better fit than the linear model?ThenExponential modelExcel gave me y=2E-08e to the power of 0.0156xHow well does the exponential model fit the data? Is it a better fit than the linear or quadratic models?I'm then asked which regression model makes since to find out what the population would be in 20 years.
