    did i do this correctly

    for a parabola f(x) = X^2
    1) state minimum and maximum
    minimum is 0
    maximum is ?: would it be ∞ or would i say that there is no maximum?

    2) intervals of increasing/decreasing
    increasing: (0, ∞)
    decreasing: (-∞ , 0)

    You did do this correctly.

    You say a function has no maximum. A maximum of infinity is meaningless, as the maximum defines the highest point.
