WHAT DOES CLOSE AND OPEN INTERVAL MEAN

Asked by prkriti GUPTA | 1st Sep, 2012, 07:24: AM

Expert Answer:

An open interval does not include its endpoints, and is indicated with parentheses. For example (0,1) means greater than 0 and less than 1.
 
A closed interval includes its endpoints, and is denoted with square brackets. For example [0,1] means greater than or equal to 0 and less than or equal to 1.
