(a) Find a function f that gives the income tax on an income x in €. Express fas a piecewise defined function. if 0 sxs 20,000 if x > 20,000 (b) Find f if 0sxs 4000 (x) = if x > 4000 What does f represent? OF1 represents the taxpayers' income under €20,000 when x dollars are paid in taxes. OF! represents the taxpayers' income over €20,000 when x dollars are paid in taxes. O F! represents the taxpayers' tax rate when their income is x dollars. OF! represents the taxpayers' total income tax when their income is x dollars.
