I am having a mental block. I have the answer to the question. It is
(-‡,‡). I just need help figuring it out. The equation is:


  • Calculus - ,

    If you meant (-&infin,+&infin), your answer is correct.
    1 is already >0, and x^2 is ≥0 ∀x∈R, therefore x∈R will satisfy the given inequality.

    To post ∞, you can type:
    & i n f i n ;
    without typing the intevening spaces.
    The "Microsoft Word" symbols/alt-code are not interpreted correctly here.
