I need help with giving an example of a function that is defined on the set of integers that isnot a one-to-one function. Identify two values that are mapped to the same value to demonstrate that it is not one-to-one. Give an example of a function that is defined on the set of rational numbers that is not an onto function. Identify one value that is not mapped to, to demonstrate that it is not onto. Give an example of a function defined on the real numbers that is a one-to-one correspondence. Define the inverse of that function.

Helping with with everything listed would greatly help me better understand my course work.
