A.4.17.1 Water in a Tank
A tank contained some water. The function w represents the relationship between t, time in minutes, and the amount of water in the tank in liters. The equation w(t)=80-2.5t defines this function.
1. Sketch a graph of the function. Be sure to label the axes.
2. How is the water in the tank changing? Be as specific as possible. 3. What does w(t) represent? Is w(t) the input or the output of this function?
