The set (-∞, -11] U [-8, ∞) can be expressed as -∞<x<=-8 and -11<=x<∞.
Given a set (-∞, -11] U [-8, ∞).
We are required to express the set in inequality notation.
Inequality is like an equation showing the relationship between two or more variables mostly expressed in greater than,less than, greater than or equal to, less than or equal to signs.
Set is a collection of things expressed in brackets.
The set which is given is (-∞, -11] U [-8, ∞).
From the above set the value of x ranges to -∞ to -8 and the value of y ranges from -11 to ∞.
Hence the set (-∞, -11] U [-8, ∞) can be expressed as -∞<x<=-8 and -11<=x<∞.
