Exercise 4.2.2: Properties of algebraic functions. About For each of the functions below, indicate whether the function is onto, one-to-one, neither or both. If the function is not onto or not one-to-one, give an example showing why (a) ERR. f(x) = x2 Solution Not onto. Let y be a real number such that y
