The left side continues down, and the right side continues down.

Step-by-step explanation:

The end behavior of the polynomial is ruled by the value of highest order coefficient and the order of the polynomial. An even order indicates the same behaviour on both sides and the sign of the highest order coefficient indicate if function goes up (positive) or down (negative).

In this case, left and right continues down.

B.) The left side continues down, and the right side continues down.

Step-by-step explanation:

if you solve f (x) = -4x^4 + 4x^3 + 9x^2 - 12x + 10 its f (0) = 10 and you graph that and you get BThe left side continues down, and the right side continues down.
