Answer:

Domain of f:W

Range:W

Step-by-step explanation:

We are given that a function

[tex]f:W\rightarrow W[/tex]

Whole number set(W); It starts with zero .

W={0,1,2,3,4,....}

We are given that assign each whole number to its largest place  value digit.

f(4)=4

f(124)=4

We have to find the domain and range of f.

Domain: It is defined as the set of values which are assign.

Range: It is defined as the set of value which are obtained corresponding to assign values.

So,

Domain of f:W

Range:W
