Answer:
f(x)=0.0000424x²−0.165x+160.126
The coefficient of determination (r^2) for this quadratic regression model is a measure of how well the quadratic function fits the data. It is a value between 0 and 1, where a higher value indicates a better fit. The r^2 value for this regression model is approximately
0.970
0.970, suggesting a strong correlation between the quadratic function and the given data.
