A population of bacteria is treated with an antibiotic. It is estimated that 5,000 live bacteria existed in the sample in 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?

The answer is A. f(x) = 5000(0.4)x, with a horizontal asymptote of y = 0, because 2,000 of the bacteria remain alive.

Step-by-step explanation:

step-by-step explanation:

through just a quick inspection, one can see that the graph of this cubing function starts in quadrant iii and ends in quadrant i.   when x = 0, y = 3, so the y-intercept is (0, 3).
