A population of bacteria is treated with an antibiotic. It is estimated that 5,000 live bacteria existed in the sample before treatment. After each day of treatment, 40% of the sample remains alive. Which best describes the graph of the function that represents the number of live bacteria after x days of treatment

f (x) = 5000 (0.4) x, with a horizontal asymptote of y = 0

f (x) = 5000 (0.6) x, with a vertical asymptote of x = 0

f (x) = 5000 (1.4) x, with a horizontal asymptote of y = 0

f (x) = 5000 (1.6) x, with a vertical asymptote of x = 0
