For each of these functions is it onetoone Is it onto For ea

For each of these functions, is it one-to-one? Is it onto?

For each of these functions, is it one-to-one? Is it onto? For each of these functions, is it one-to-one? Is it onto? (recall that the range [0. infinite) is the non-negative real numbers)

Solution

all functions are onto function because all functions have square operation.
