-4x

<-- Enter Numerical Statement

Display the interval notation and set builder notation for -4x<0

Since our variable of x has a coefficient of -4, we first divide each side of the inequality by -4
Since -4 is less than zero, inequalities state we need to reverse our sign from < to >

x>0 ←This is the modified expression we use going forward

You entered the greater than sign in the expression x>0
We start with the left side of the interval notation

Build the interval notation for x:
Since you did not enter an equal sign, this translates to ( since we will not be including the number 0
Based on the > you entered, the right side of the interval notation will extend to positive infinity, which is denoted as +∞

(0,+∞)

Set Builder Notation for x:
{ x | x>0 } where | denotes such that
