Algebra 2 Honor Help Needed!!

13) and (13,the () means not included.......
Hi I'm new to this forum and I'd have a question about Alg. 2
The question is: put this into interval notation: all real numbers greater than or equal to 7, but not equal to 13.

I answered it as [7, Positive Infinite) or (13, Positive Infinite).
Is my answer valid to a certain extent?
