a. Let a function from the real numbers to the integers be defined by f(x) = [x]. Is f one-to-one? Is f onto? Explain why or why not in each case. Xx b. Let f: Z→→ Z be defined by f(x) = [x]. Is f one-to- one? Is fonto? Explain why or why not in each case. a. Let a function from the real numbers to the integers be defined by f(x) = [x]. Is f one-to-one? Is f onto?
