Linear Regression Question
What is linear regression? Fit the linear function to the following data.
$$\begin{array}{c|cccccccc} x & 1.0 & 1.2 & 1.4 & 1.6 & 1.8 & 2.0 & 2.2 & 2.4 \ \hline f(x) & 2.0 & 2.6 & 3.9 & 6.0 & 9.3 & 15.0 & 20.6 & 30.4 \end{array}$$

Linear regression is a curve-fitting technique that determines the best-fit straight line through a set of data points using the least squares principle, which minimizes the sum of squares of the residuals (vertical deviations) between observed values and the line. The model is: $$f(x) = a0 + a1 ...
