Answer:
See answers below
Step-by-step explanation
A) For the function;
x < 0
since the values of x are less than zero, and towards the left of the number line hence the interval is decreasing.
B) 0For the interval, the values fall between 0 and 2, this shows that the values are increasing since they are positive values towards the right hand of the number line.
C) 2This is also similar to the interval in B, hence this is also increasing
D) For x > 4
The values greater than 4 are 5, 6, 7, 8...you can see that the values are also increasing. Hence the given interval is also increasing
