Homework Sourse1 Use fx to find the cumulative number of AIDS deaths in 200
1. Use f(x) to find the cumulative number of AIDS deaths in 2000.
2. Use g(x) to find the cumulative number of AIDS in 2000.
3. Which function is a better description for the actual number shown in the bar graph?
a) g(x)
b) f(x)
c) cannot be determined.
Solution
solution:
f(x) =-2210x2+57,573x+107,895
g(x) = -82x3-704x2+50,604x+113,431
The cumulative number of AIDS deaths in 2000 is f(2000-1900),g(2000-1900)
1. f(10) = -2210(10)2+57,573(10)+107,895
= 46,2625
2. g(10) = -82(10)3-704(10)2+50,604(10)+113,431
= 46,7071
3. b) f(x)
