To find the interval for the first piece, find where the inside of the absolute value is non-negative.
x+23≥0
Solve the inequality.
Tap for more steps…
Multiply both sides of the equation by 3.
x+2≥0⋅(3)
Remove parentheses.
x+2≥0⋅(3)
Multiply 0 by 3.
x+2≥0
Subtract 2 from both sides of the inequality.
x≥-2
x≥-2
In the piece where x+23 is non-negative, remove the absolute value.
x+23<1
To find the interval for the second piece, find where the inside of the absolute value is negative.
x+23<0
Solve the inequality.
Tap for more steps…
Multiply both sides of the equation by 3.
x+2<0⋅(3)
Remove parentheses.
x+2<0⋅(3)
Multiply 0 by 3.
x+2<0
Subtract 2 from both sides of the inequality.
x<-2
x<-2
In the piece where x+23 is negative, remove the absolute value and multiply by -1.
-x+23<1
Write as a piecewise.
{x+23<1x≥-2-x+23<1x<-2
{x+23<1x≥-2-x+23<1x<-2
