Answer

Explanation:

Step1: Identify increasing intervals

Observe where graph rises.

Step2: Identify decreasing intervals

Observe where graph falls.

Step3: Identify constant intervals

Observe where graph is horizontal.

Step4: Find domain

All x - values covered by graph.

Step5: Find range

All y - values covered by graph.
