Final answer:
In interval notation, [3,6) represents the set of real numbers from 3 to 6, including 3 but not 6.
Step-by-step explanation:
In interval notation, the notation [3,6) represents the set of real numbers between 3 and 6, including 3 but not including 6. This means that every real number that is greater than or equal to 3 and less than 6 is part of the set. The brackets [ and ) are used to indicate which endpoints are included in the set: the square bracket [ means that the endpoint is included, and the parenthesis ) means the endpoint is not included. Therefore, the number 3 is part of this set, but the number 6 is not, as the interval goes up to, but does not include, the number 6.
