Strict inequalities express ordering relationships using the symbol for less than and for greater than imply that solutions may get very close to the boundary point in this case 2 but not actually include it.

When using set notation inequality symbols such as are used to describe the domain and range. Therefore this statement can be read as the range is the set of all y such that y is greater than or equal to zero.
