[-3,1)
-x-6<_-3 add 6 both sides
-x<_3 divide by negative 1 which means sign switches
x>_-3
-4x+3>-1 subtract 3 both sides
-4x>-4 divide by negative 4 which means sign switches
x<1
1 is the greater bound meaning x can’t be larger than 1
the sign doesn’t include 1 so it’s the parenthesis in interval notation
-3 is the lower bound meaning x can’t be -3 or less than -3 so the interval notation is
The sign includes -3 so it’s brackets in interval notation
