I need Help!! 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

a

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

Step-by-step explanation:

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

Step-by-step explanation:

The function is in the form

y = a b^x

where a is the initial value and b is the growth (or decay rate)

a = 5000 and b = 40 %

(If we have been given 40 % dies off we would have taken 1-40% or 1- .4)

y = 5000 ( .4) ^x

This has a horizontal asymptote at y = 0 because we will never get to 0 bacteria.  There will always be part of a bacterial left

the answer would be d

straight away you can eliminate a and c because not all books contain a scientific skill because some may be fiction. c is also wrong because it saids that the only way children can learn is through books which is incorrect.

b is also wrong because reading can be a scientific skill but not always, therefore it is wrong which leaves you with d, the correct answer since it said that it can children learn.

hope this ! : 3

answer: y = 3/2 x - 3

y = 1/8 x - 3/4 that would be your correct option
