    Help with Functions

    Why does this equation define "y" as a function of "x" ? What would I need to know to answer this question?

    x+y=1

    x+y=1
    Definition (from Wikipedia):

    A function from a set X to a set Y associates to each element x in X an element y = (x) in Y.
    Apply the definition to y = \sqrt[3]{1 - x^3}.
