Homework Help: Write down the domain and range of the function

  1. Aug 6, 2008 #1
    Write down the domain and range of the function
    g(x) = 1 / ((9 - x)2)

    Please enter your answer as a list [in brackets], using inequalities e.g. a domain (for x) of (-¥, 2) and a range (for g(x)) of (2, 5] may be entered as:
    [x < 2, 2 < g(x) and g(x) <= 5]

    I don't get it??

    Re: function

    What specifically don't you understand? The question or the notation?

    Re: function

    The very first thing you should do is check the definitions of "domain" and "range". Look them up in the index of your textbook.
