Answer #1

Answer: True

Explanation: Given set is {-3,-2,-1}

                     And the statement is {x belongs to R | -3<=x<=-1}

                     x belongs to R means x is in range between {-infinity,infinity} and the condition -3<=x<=-1 gives

                     three numbers only {-3,-2,-1} and is equal to given set.So it is True.
