Kira drained an aquarium. She took 20 minutes. The graph shows the amount of water (in liters) in the aquarium versus time (in minutes). Find the domain and the range of the function shown.

D: {0≤x≤20}

R: {0≤y≤200}

Step-by-step explanation:

Domain and range are the possible values of x and y, respectively. For continuous graphs in set notation, inequalities can be used to represent the x and y values. As seen on the graph, the lowest possible x value is 0 and the highest is 20. All of the other values in between are also included. So the inequality 0≤x≤20 expresses all of the values. Additionally, because the circles are closed, the limit values, 0 and 20, are included. Next, the range is found in the same way. The lowest y is 0 and the highest is 200, with the limits included. So, the range inequality is 0≤y≤200.
