Expert Solution

Step 1: The Ceiling Function
The Ceiling Function is defined as the smallest integer that is not smaller than . It is the opposite of The Floor Function or the Greatest Integer function. It is denoted by
.
For example whereas
.
The given function is
Check injective is one one function if
Check surjective is onto function if for every
