Question

A swimming pool is initially shocked with chlorine to bring the chlorine concentration to ppm (parts per million). Chlorine dissipates in reaction to bacteria and sun at a rate of about per day. Above a chlorine concentration of ppm, swimmers experience burning eyes, and below a concentration of 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.
