Answer
(E) and (G)
increase: $(0,\infty)$
decrease: $(-\infty,0)$
Work Step by Step
We can see that graphs (E) and (G) decrease over intervals in their domains and increase over other intervals. Both of these graphs increase over positive $x$ values and decrease over negative $x$ values:
increase: $(0,\infty)$
decrease: $(-\infty,0)$
