[-8,infinity)
represents the interval from -8 inclusively [ to infinity exclusively ).
[] are used to mean including the limits.
() or ][ are used to mean excluding the limits.
The above interval is the same as
-8 ≤ x < ∞
Is this [-8,infinity) the same as this x < -8 OR x > 1 ? Thank you.
Based on what is below is below, is what is above = to the same? Thanks!
