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

Step-by-step explanation:

f (x) = - 4x⁴ + 4x³ + 9x² - 12x + 10

The leading term (-4x⁴) has an even exponent and a negative coefficient.

Since the exponent is even, the left and right ends will continue in the same direction.

Since the coefficient is negative, both ends will continue down.
