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??

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


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