Question

How do you find the end behavior of `f(x) = –x^4 – 4`?

Answer 1

`-infty`

Explanation:

We know that any polynomial will tend to positive or negative infinity.

We can determine which one by the sign of the coefficient in front of the leading term. Here, the leading term is `-x^4` and since that coefficient is negative, the function will limit to negative infinity.
