Answer:
see explanation
Step-by-step explanation:
To determine the end behaviour, we only need to consider the term of highest degree, that is the leading term in standard form
The term of highest degree in f(x) is 4![x^{5}](https://tex.z-dn.net/?f=x%5E%7B5%7D)
which is of odd degree with positive coefficient
As a result the end behaviour is
As x → + ∞ (right), f(x) → + ∞ ( that is rises )
As x → - ∞ (left), f(x) → - ∞ ( that is falls )
