Considering the last thread was so incredibly helpful I decided to post yet again. Sorry for creating another thread!
I have the equation: f(x)=1/x^2-9 written in my textbook and the question states "find the domain and range of f(x)"
I have never seen something similar to this and was wondering how I'm meant to work out the domain and range or find it withing the equation? is there a specific formula for finding it?
Also, how are we able to tell if f(x) is even, odd or neither?
