Is this [-8,infinity) the same as this x < -8 OR x > 1 ? Thank you.
[-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!

Your last line is not legible under Western nor unicode encoding. It is however, the correct answer under GB2312 encoding.
No, [-8, infinity) is not the same as x < -8 OR x > 1.
The interval notation [-8, infinity) represents the set of all real numbers from -8 to positive infinity, including -8 but not including positive infinity. This means that any value of x greater than or equal to -8 would be included in this set.
On the other hand, the inequality x < -8 OR x > 1 represents two separate conditions. The first condition, x < -8, means that any value of x less than -8 would satisfy this inequality. The second condition, x > 1, means that any value of x greater than 1 would satisfy this inequality. So, the values of x can either be less than -8 or greater than 1, but not both at the same time.
In summary, [-8, infinity) represents the set of all real numbers greater than or equal to -8, while x < -8 OR x > 1 represents the set of all real numbers that are less than -8 or greater than 1. These two expressions are not equivalent.
