WebThis type of interval includes only one of the endpoints of the inequality. For example, the set {x -3 ≤ x < 1} include the endpoint -3. This is expressed using half-open interval notation: [-3,1) Notations For Different Types of Intervals We can follow certain rules and symbols to represent the interval notation for different types of intervals. http://www.ifp.illinois.edu/~angelia/L4_closedfunc.pdf the end update bedrock https://a-kpromo.com
