    odd degrees are functionable; even degrees need a restricted domain

    Choice #3 inverse is not a function: x = -|y| -> x = -(-y) or -y -> x = y or -y 2 different values of y for each x except for at the origin.

    The 2 graphs in each post show the function and the inverse to the right of it. A picture tells a thousand words.

    graphwise .... -|x| is basically the same as -x^2

    I dont really understand the graphs... I know the third one isn't a function and I'm guessing the first isn't either...

    x^(even) is not invertible without restricting its domain x^(odd) is invertible
