- as x increases, f(x) decreases;
- as x decreases,f(x) decreases
Step-by-step explanation:

- as x increases, f(x) decreases;
- as x decreases,f(x) decreases
_____
<em>Even degree</em> means the end behaviors are the same for both large and small x. <em>Negative leading coefficient</em> means the function value decreases for larger x.
