The built-in range function consumes an integer and returns numbers from 0 up until that integer. This can be used to plot mathematical expressions.
We have used the function to create a list of X values stored in the variable xs - now you can use that list to create a list of corresponding Y values, and then plot that list as a line plot that models the parabolic equation:
You do not need to label the graph. Call plt.show() to display the plot.
