Answer:

1. Increasing on ( -inf, -3] and ( 3, inf)

2. decreasing on (-3, 3]

3. Local maximum: 60, Local minimum: -60

4. Domain: (-inf , inf)

Range: [-60, 60]

Explanation:

1.

A function is increasing when its slope is positive. Now, in our case we can see that the slope of f(x) is postive from - infinity to -3 and then it is negatvie from -3 to 3; it again increasing from 3 to infinity.

Therefore, we c
