Answer:
increasing: x > 0
Explanation:
Given a table of function values, you want to know the interval on which the function is increasing.
Increasing
A function is increasing if f(x)-values get larger when x-values get larger. As we go down the table, the x-values get larger.
In the first three lines of the table, the f(x)-values are getting smaller. The function is decreasing on that interval, x < 0.
In the last three lines of the table, the f(x) values are getting larger. The function is increasing on that interval, x > 0.

Additional comment
The point (0, 0) represents a minimum. The function is not increasing or decreasing at that point, so the interval of interest is x > 0, not x ≥ 0.
