color(white)("d")

Input comes before you can get an output

the letter d (for domain) is alphabetically before the letter r (for range).

So d

So r

We are told that

The range is every

Mathematically we are not 'allowed' to have 0 as a denominator. This situation is called **'the function is undefined'.**

Thus we have

Add 3 to both sides

Consequently the input (domain) all

domain is the set of
