Polynomial Regression Algorithm in Machine Learning

What will you do if your data is a bit more complicated than a straight line? A good alternative for you is that you can use a linear model to fit in a nonlinear data. You can use the add powers of ever feature as the new features, and then you can use the new set of features to train a Linear Model. In Machine Learning, this technique is known as Polynomial Regression. Let's understand Polynomial Regression from an example.
