The graphs of pool A and pool B are illustrations of piece-wise functions
The rate of both pools from t1 to t2, t is 0.
How to determine the rates of the graphs
From 0 to t1, the rates of the pools are:
Pool A = A/t1
Pool B = B/t1
Where A represents the gallons of water in the pool and B represents the rate at time t1
From t1 to t2, the rate of both pools is 0.
This is so because both intervals are represented by horizontal lines
