Answer: decreasing from -4 to -1, increasinc from -1 to zero, decreasing from zero to 1, and increasing from 1 to 3
Step-by-step explanation:
The given function is increasing in the given interval (1, 3).
A function represents the relation between two sets. One is the domain set and the other one is the range set.
Here, it is clear that:
1. The graph y = f(x) is decreasing in the interval (- 3, - 1).
2. The graph y = f(x) is increasing in the interval (- 1, 0).
3. The graph y = f(x) is again decreasing in the interval (0, 1).
4. The graph y = f(x) is again increasing in the interval (1, 3).
Therefore, in the given interval the function y = f(x) is increasing.
