    Need help finding the domain and range of this inverse trig function.

    What are the domain and range, respectively, of the function y = arcsin(3x)?

    I believe it is this (http://castlelearning.com/review/Cou...lc/q4398-2.gif) but I am not sure, can anybody help me find it? Please and thank you.

    Your domain is correct, but your range is wrong. Draw the graph to get the range.
