Since I cannot see the graph you're referring to, I'll guide you through creating a statement and analyzing the increasing and decreasing intervals based on typical behavior you might expect in a graph representing an account balance over time.

Model Statement:

"The balance of James's account changes over time, reflecting deposits and withdrawals. The graph shows how the balance increases or decreases as time progresses."

Increasing Interval:

  • When is the function increasing? The function is increasing during any time interval where the graph slopes upward. This could represent times when James is making deposits into his account.

  • Relation to your statement: During these intervals, James is likely depositing money, resulting in a higher account balance with the passing of time. This correlates with the notion that his financial situation is positively affected during these periods.

Decreasing Interval:

  • When is the function decreasing? The function is decreasing during any time interval where the graph slopes downward. This might represent times when James is making withdrawals from his account.

  • Relation to your statement: During these intervals, James is likely withdrawing money, which causes his account balance to drop over time. This indicates a negative impact on his financial status during these periods, illustrating the importance of managing withdrawals in relation to his spending and saving habits.

Summary:

While discussing the graph, you would emphasize that the periods of increasing and decreasing balances reflect James's financial activities—deposits versus withdrawals—over time, showcasing how they affect his overall account balance.

Thank you for providing the graph details! Based on the information you've given, here's how we can analyze the situation.

Model Statement:

"The balance of James's account over a 14-hour period shows fluctuations as he makes various transactions. The balance rises during certain hours due to deposits and drops during others due to withdrawals."

Increasing Interval:

  • When is the function increasing?
    The function is increasing during the intervals where the graph slopes upward. From the graph, it looks like the balance rises:

    • Between hours 0 and 2
    • Between hours 6 and 10
  • Relation to your statement:
    During these intervals, James is making deposits into his account, leading to an increase in his overall balance. This reflects positive cash flow in his financial activities during this time.

Decreasing Interval:

  • When is the function decreasing?
    The function is decreasing during the intervals where the graph slopes downward. According to your graph, the balance drops:

    • Between hours 2 and 4
    • Between hours 4 and 6
    • After hour 10 until hour 14
  • Relation to your statement:
    During these intervals, James is withdrawing money, which leads to a decrease in his account balance. This indicates that he is spending more than he is depositing during those hours, resulting in a negative impact on his financial situation.

Summary:

In summary, the graph effectively captures James's financial activity over time. The points where the graph rises signify periods of deposit, while the points where it falls indicate withdrawals. Analyzing these intervals can provide insight into how James manages his account balance and makes decisions regarding saving and spending.
