b) Write a piecewise-defined function for the income of an author (f(x)) who earns $10 for each book sold (x) when the number of sales is less than or equal to 1000. If the number of sales is over 1000, then the author earns an $12 for each book sold over 1000. Begin by calculating the income when no books are sold and when exactly 2000 books are sold. Confirm that your function is correct for these values.
