Answer:
x ∈ IR / or you can also write
x ∈ IR / x ∈ [-2 , + ∞)
Step-by-step explanation:
We have the following inequality :
To find the solution set of the inequality we need to find the values of x that satisfy the inequality.
Working with the inequality :
The solutions of the inequality are all real numbers greater or equal to -2
We can write this as
x ∈ IR /
Or either using and interval as
x ∈ IR / x ∈ [-2 , + ∞)
