Optional Task The powerful thing about this form of expression is its extensibility. For example, we can move from a linear equation to a quadratic equation or even a cubic equation! Open up optional_task.py; you should see some similar code to that for Compulsory Task 1 . The main difference is that the X values now range from 100 to 100 , and the parameter vector now has 4 values. - Plot the graph of f(x)=PX. If all went well in the first task, this shouldn't warrant any changes to your code. - Your resultant graph should look something like this: If you are having any difficulties, please feel free to contact a code reviewer for support
