ANSWER :
As x goes to ∞, f(x) goes to -∞
EXPLANATION :
From the problem, we have the power function :
![f(x)=-2x^3](https://img.qammunity.org/2023/formulas/mathematics/college/25i1p3zs1rv65ykhyu4zzitdvdscsj1rn7.png)
As x goes to infinity, the value of x^3 is always positive.
multiplied by -2, the result will be negative.
So the end behavior of f(x) as x goes to ∞ is -∞
