Question

The owners of a recreation area filled a small pond with water in 120 minutes. the pond already had some water at the beginning. The graph shows the amount of water ( in liters) in the pond versus time (in minutes). What is the domain and range for this problem?

Answer 1

The domain for this problem is all real numbers greater than or equal to zero, and the range is all real numbers greater than or equal to the initial amount of water in the pond.

Step-by-step explanation:

The domain of a function represents all the possible input values or independent variables. In this case, the independent variable is time, which is measured in minutes. So the domain for this problem is the set of all possible values of time, which is all real numbers greater than or equal to zero.

The range of a function represents all the possible output values or dependent variables. In this case, the dependent variable is the amount of water in liters. Looking at the graph, we can see that the amount of water starts at a certain value and increases over time. Therefore, the range for this problem is all real numbers greater than or equal to the initial amount of water in the pond.
