Aswimming pool is initially shocked with chlorine to bring the chlorine concentration to 6 ppm (parts per million). chlorine dissipates in reaction to bacteria and sun at a rate of about 15% per day. above a chlorine concentration of 2 ppm, swimmers experience burning eyes, and below a concentration of 1 ppm, bacteria and algea start to proliferate in the pool environment.
a. construct an exponential decay function that describes the chlorine concentration (in parts per million) over time.
