Describe the end behavior of the polynomial by
finding X-> ∞ and X-> -∞
F(X) =X^3 - 7x^2 +2x-1
Can you please help me step by step . thank you in advance :)
----------------------------------
The x^3 term determines the value of
F(x) as x goes to +inf and x goes to -inf.
------------------------
As x goes to +inf, X^3 goes to +inf, so F(x) goes to +inf.
----
As x goes to -inf, X^3 goes to -inf, so F(x) goes to -inf.
