As x approaches --, f(x) approaches
As x approaches +o, f(x) approaches​

Answer 1

9514 1404 393

Answer:

(x, y) → (-∞, -∞), (+∞, +∞)

Explanation:

The expression is of odd degree with a positive leading coefficient. It will have a generally upward slope (/). That is, the sign of f(x) will match the sign of x for large-magnitude values of x:

x → -∞, f(x) → -∞

x → ∞, f(x) → ∞
