O f(x) → -2
O f(x) → + 0
O f(x) → 2

    Answer:

    first option f(x) -> negative infinity

    Step-by-step explanation:

    the other answer is sadly wrong.

    there is a “-” in front of the expression.

    -2x³ had two parts

    -2, which is multiplied to x³

    now x³ goes to (positive) infinity for x going to (positive) infinity.

    but because this is multiplied by a negative value (-2), all the functional values for positive x are negative.

    therefore, the function goes to negative infinity for x going to (positive) infinity.
