Answer:
Option D is correct.
Step-by-step explanation:
We can see from the attachment which is graph with all four possibilities
Odd function and positive "a" which is red graph
Even function positive "a" which is blue graph
Odd function negative "a" which is green graph
Even function negative "a" which is purple graph
Let us assume values of "a" and "n" according to the possibilities.
The required behaviour which is As x > 0 increases, f(x) decreases. As x < 0 decreases, f(x) decreases is shown by purple graph that is odd monomial function with negative "a".
Therefore, Option D is correct.
