For end behavior, we need to consider 2 things: the highest exponent, and the coefficient of the highest exponent. the highest exponent is 6, an even number, which means that the end behaviors will both be ∞ or -∞. Since the coefficient is -4, a negative number, the end behaviors will both be -∞. As x→ -∞, f(x)→ -∞. As x→ ∞, f(x)→ -∞.
