Answer:
[-1;∞)
Step-by-step explanation:
The lowest number is always written on the left side in the interval notation. the interval notation uses parentheses for exclusive sets and brackets for inclusive sets. Let's say you have two numbers m & n and m<x<n, then to write in interval notation, you would write (m,n). If m ≥x ≥ n then, [n,m].
