Given f as described below.
f: {whole numbers} → {whole numbers}
assign each whole number to its largest place value digit.
for example, f(4) = 4, f(14) = 4, and f(194) = 9.
a. what is the domain and range of f?

Domain of f:W

Range:W

Step-by-step explanation:

We are given that a function

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

step-by-step explanation:

$3720

step-by-step explanation:

taxable income = $31000

as per the 2018-2019 us tax bracket, the tax rate is 12% for an individual whose taxable income is between $9,526 to $38,700.

so, the tax to be paid by him = 12% of 31000

= 0.12 * 31000     [12% converted to decimal as 0.12]

= $3720
