 # -4x

## Enter inequality for interval notation:

Display the interval notation for:
-4x<0

## Interval Notation Definition:

An interval as a set of numbers.
Numbers = endpoints.
Since our variable of x has a coefficient of -4
Divide each side of the inequality by -4
Since -4 < 0
Reverse our sign from < to >
 -4x -4
 >
 0 -4

x>0  ←Use this expression going forward

You entered the > sign
Start on the left side of x>0

## Build the interval notation for x:

No equal sign translates to (.
Do not include the number 0
The right side extends to +∞  ## Set Builder Notation for x:

{ x | x>0 } where | denotes such that

## Display the literal notation for x
