Question

which graph could represent a constant balance in a bank account over time? balance (dollars) daily balance time (days) balance (dollars) daily balance time (days) balance (dollars) daily balance time (days) balance (dollars) daily balance time (days)

Explanation:

Step1: Understand constant - balance concept

A constant balance means the balance does not change over time. On a graph with time on the x - axis and balance on the y - axis, it will be a horizontal line.

Step2: Analyze each graph

The first graph has a line with a positive slope, meaning the balance is increasing over time. The second graph has a horizontal line, indicating the balance remains the same over time. The third graph has a negative slope, meaning the balance is decreasing over time. The fourth graph has a vertical line which is not a valid representation of a function (a single time value cannot have multiple balance values).

Answer:

The second graph (the one with the horizontal line) could represent a constant balance in a bank account over time.
