Question 6 • ****Summer 2026 Common Core Algebra I - MA3109 B-IC MEF22QXV
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?
Answer
A
f(x) = 5000(0.4)x, with a horizontal asymptote of y = 0
B
f(x) = 5000(0.6)x, with a vertical asymptote of x = 0
C
f(x) = 5000(1.4)x, with a horizontal asymptote of y = 0
D
f(x) = 5000(1.6)x, with a vertical asymptote of x = 0
