    [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 f = the range of f^{-1}

    The range of f = the domain of f^{-1}

    Your answer could be correct. What is f ?

    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.
