# Thread: How do you find the domain and the range of a hyperbola

1. ## How do you find the domain and the range of a hyperbola

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?

2. What is the equation of the hyperbola? I opened your attachment and didn't see anything.

3. ## I hope you can see it, i couldnt figure out how to paste it in the forum

The exponet is a 2,

4. 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.

5. Actually, I don't think the graph is defined at y=0, this means that the range is (-infinity,0)U(0,infinity). with a domain that is (-infinity, -3)U(3,infinity).
