What is the equation of the hyperbola? I opened your attachment and didn't see anything.
I am trying to do an extra credit assingment, and it ask that i find the domain and range of a hyperbola graph.
I have attached an example problem and I think I did the graph correctly, can someone please help me?
I would say that the range of this graph is (-infinity,infinity) and the domain is (-infinity,-3]U[3, infinity).
By setting y=0 and solving for the value of x, which is 3 and -3, explains why the range is what it is. The graph is not defined between (-3, 3).
I think this is correct, but I may be wrong on the domain, but I'm pretty sure it's right.
