    Because I've helped you with plenty of these exact kinds of problems. You should understand how to do them by now.

    And you probably still haven't learned how to use your graphing calc.

    ohhh haha :P yeah i just don't know how to tell if its the graph with that particular kind of function... we've done other kinds of functions b4 but not these kinds... and I'm still not too familiar with my graphing calc... but yeah we did other kinds of functions b4 :/

    lol normally you can also use the general form of a cube \[y=x^3\] \[y^{-1}=x^{1/3}\]FORM|dw:1353890445166:dw| |dw:1353890513388:dw|

    Actually, there was a negative sign afront that function, so you also have to flip it over the x-axis as well @jonask

    |dw:1353892609349:dw| |dw:1353892711812:dw|so we need to put - in front ie reflect in x-axis(y become -y) |dw:1353892786065:dw|
