A seagull is tired and decides to fly down and sit in a wave pool. Due to the waves, the seagull is going up and down. After 10 seconds, the seagull is at its maximum height, 9 feet above the bottom of the pool. Every 20 seconds, the seagull returns to that high point. At its lowest, the seagull is 3 feet above the bottom of the pool. Create a sketch. Must draw on your own paper. Remember to label your axes.
