What is the end behavior of the graph of the polynomial function f(x) = –x5 + 9x4 – 18x3?
2 answers:
Answer:
As x approaches ∞, y approaches -∞
As x approaches -∞, y approaches ∞
Step-by-step explanation:
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
