x is greater then -2 in interval notation

Question

 x > -2 in interval notation

Answer 1

x > -2

 

In interval notation:

 

(-2,∞)

 

The numbers are the endpoints of the interval.  Use parentheses () if the endpoint is not included (< or >); use brackets [] if the endpoint is included (≤ or ≥).  ∞ is never included, so always use parentheses for ∞.
