Describe the end behavior of the following function:
Furkat [3]

Answer:

C. The graph of the function starts high and ends low

Step-by-step explanation:

For f(x)=-x^5+x^2-x, as x approaches negative infinity, f(x) approaches infinity, and as x approaches infinity, f(x) approaches negative infinity.

Thus, we have:

\lim_{x\rightarrow -\infty}f(x)=\infty,\\\lim_{x\rightarrow \infty}f(x)=-\infty

This corresponds with answer choice C. The graph of the function starts high and ends low.
