Thread: [GRAPH] What are the domain and range of f -1? (domain) (range)

What are the domain and range of f ^ -1? (It's an inverse right?)

I got
Domain : (-INFINITY, INFINITY)
Range : (-INFINITY, INFINITY)
Is this correct?

The domain of = the range of

The range of = the domain of

Your answer could be correct. What is ?

if f is restricted to the values on the graph, then the domain of f is [-3,3] and the range of f would be [-1,3].

... if the function continues outside the visible graph, then there is no way to tell w/o more information about f.

thanks i got the first part right but [_,3] domain and [_,3] I didn't get the x for both of them right...
