Display the interval notation for:
9j>36
An interval as a set of numbers.
Numbers = endpoints.
We get interval notation by saying 9j>36
Since our variable of j has a coefficient of 9
Divide each side of the inequality by 9
9j | |
9 |
> |
36 |
9 |
j>4 ←Use this expression going forward
You entered the > sign
No equal sign translates to (.
Do not include the number 4
Based on the > you entered,
the right side of the interval notation will extend to positive infinity,
which is denoted as +∞
{ j | j>4 } where | denotes such that
5,6,7,8,9,10,11,12,13,14,...,∞
