    Completely Simplifying Quadratics

    3. What does -∞ mean? (negative infinity?)

    What does -∞ mean? (negative infinity?)

    Javobi bilan

    When I was practicing limits, the answer to one of the questions was -∞.  Does this mean ¨negative infinity¨?  What does ¨negative infinity¨ mean?
