Answer
Explanation:
Step1: Analyze the graph
When the phone is plugged into the charger, the battery - life percentage will increase or stay at 100%. On the graph, we look for the intervals where the battery - life is increasing or constant.
Step2: Check each time option
For 6 hours: The graph is decreasing at 6 hours, so the phone is not charging. For 9 hours: The graph is increasing at 9 hours, so the phone could be charging. For 11 hours: The graph is decreasing at 11 hours, so the phone is not charging. For 14 hours: The graph is increasing at 14 hours, so the phone could be charging. For 19 hours: The graph is increasing at 19 hours, so the phone could be charging.
Answer:
9 hours, 14 hours, 19 hours
