How to write this in roster form . G = { x|x is a 3-digit number less than 100 }

Sagot :

There are three methods to represent a set. :
1. Statement Form
2. Roster / Tabular Form
3. Rule of Set Builder Form

Roster/Tabular form
Here, the elements of the set are listed within the pair of brackers {} and are separated by commas. 

Thus, the answer to the question G = { x|x is a 3-digit number less than 100 } is 
G = { -100, -101, -102, -103 ... -999}

Only negative 3 -digit number will be less than 100. Thus the set is the numbers from  -100 to -999.
