Explanation:

Answer 2

As x approaches ∞, y approaches -∞

As x approaches -∞, y approaches ∞

Explanation:

`f(x) = -x^5 + 9x^4 - 18x^3`

F(x) is a fifth degree (odd function ) with negative leading coefficient

If exponent is odd and leading coefficient is negative then end behavior is

As x approaches ∞, y approaches -∞

As you go on the right , f(x) goes down

As x approaches -∞, y approaches ∞

As you go on the left , f(x) goes up
