    Interval Notation

    Hi,

    Just wanting some clarification on how, if possible, I am able to represent the inequality: -2.5 < x > 1
    using interval notation such as: x ∈ [1,3) for the interval 1 ≤ x < 3

    Re: Interval Notation

    -2.5 < x > 1 says that  x>-2.5 AND  x>1. So x\in \langle -2.5, \infty\rangle \cap \langle 1, \infty\rangle \Rightarrow x\in \langle 1, \infty\rangle
