Function Analysis: Finding Decreasing Intervals Between x=-0.45 and x=0.45

In which field does the function decrease?

Green line $x=-0.45$

Blue line $x=0.45$

Let's remember that the function increases if the $x$ and $y$ values increase simultaneously.

On the other hand, the function decreases if the $x$ values increase while the $y$ values decrease simultaneously.

In the given graph, we notice that the function increases in the domain where $-0.45 < x < 0.45$, meaning the $y$ values are increasing.
