Display the interval notation for:
x<5or>-5
Interval Notation Definition:
An interval as a set of numbers.
Numbers = endpoints.
Account for or
Since we have an or statement
We break this up into two pieces
Piece 1 → x<5
Piece 2 → >-5
Evaluate Piece 1
Inequality Sign Evaluation
You entered the < sign
Build the interval notation for x:
No equal sign translates to ).
Do not include the number 5
Based on the < you entered,
the left side of the interval notation will extend to negative infinity,
which is denoted as -∞
Final Answer
(-∞,5)
Set Builder Notation for x:
{ x | x<5 } where | denotes such that
Evaluate Piece 2
Inequality Sign Evaluation
You entered the < sign
Build the interval notation for x:
No equal sign translates to (.
Do not include the number -5
Based on the < you entered,
the right side of the interval notation will extend to positive infinity,
which is denoted as +∞
Final Answer
(-5,+∞)
Set Builder Notation for x:
{ x | x<5 } where | denotes such that
Form our interval notation for x:
(-∞,5) U (-5,+∞)
Display the literal notation for x
-4,-3,-2,-1,0,1,2,3,4,5,...,∞
What is the Answer?
(-5,+∞)
