Answer:
Increasing
Step-by-step explanation:
A cubic function x^3 has a graph of below in the attachment.
Another method is to keep substituting from negative to positive.
(-3)^3 = -27
(-2)^3 = -8
(-1)^3 = -1
0^3 = 0
1^3 = 1
2^3 = 8
3^3 = 27
...
As you see if we keep substituting higher values, the graph or y-value will keep increasing.
Say it as y increases if x increases.
