    here is the graph of parent function: |dw:1444411348083:dw| y=3x^3 is just more impetuous, but the for this problem it doesn't matter.

    as \[x-> +oo\] what does f(x) do?

    What happens in the function (at the y axis) when the x axis goes to infinity?|dw:1444411686266:dw|

    this function doesn't have any asymptotes. as you see the function increases without bound, as x increases. so when x -> oo, the function -> oo and as x-> -oo, the f(x) -> -oo.

    if it was A, your function will look like this: |dw:1444411855361:dw|

    A says as x approaches to +oo then f(x) approaches -oo, is this statement true according to the graph?

    your graph should be |dw:1444411935971:dw|

    C is similar to B

    So then it would be D?

    yep. in D the function increases without bound as x increases and decreases as x decrease.

    I was just wanted to ask vera what she thinks the y value approaches when x approaches positive infinity.

    No, i was not correcting your draws but adding important symbols to make the graph look understandable, we also forgot to label the x and y axis.
