Answer 2

Given data: $f(x) = [x]$

To find: Smallest integer function

Solution:

• Smallest integer function is also known as the least integer function or ceiling function.
• It is used to return the smallest integer more than or equal to zero.
• For example, A = 3.4, 3.5 and B =2 then 3.4 mapped to 2 and 3.5 mapped to 2.
• From this we can say that the 2 values of element A is mapped with 1 value of element B.
• b) Hence the smallest integer function $f(x)=[x]$ is many-one.
