Describe the end behavior of the polynomial function f(x) = -2x^4 - 3x^3 +3x-5 (both as x --> ∞ and x --> -∞)
i cant remember how to write this correctly.

This polynomial is a degree 8 polynomial so its ends will go in the same direction. The negative leading coefficient (-2) indicates that that those ends will go in the negative direction, both as x approaches infinity and negative infinity.

all even degree polynomials with negative leading coefficients have the same end behavior ...
Sorry, you are correct Skeeter! My brain was thinking in factored form! Thank you for correcting!
