    Range values

    What are the possible range values of x when the set builder notation (description of set) looks like: {x | -4 =< x < 6}
    (4, 5)
    (4, -5)
    (-4, 5)
    (-4, -5)

    Are you assuming that x must be an integer? Then the set is {-4, -3, -2, -1, 0, 1, 2, 3, 4, 5}. That may be what you mean by (-4, 5) but that is not standard notation.
