Answer:
-2
Step-by-step explanation:
The functions of f(x) and g(x) are given
For f(x)+g(x)=0 , functions f and g should be in opposite sign
We can observe that at x=−2 , f(x)=2 and g(x)=−2
Therefore f(−2)+g(−2)=0
So the correct option is D (-2)
So we know that the bacteria grows 3x as much every ten minutes. From this we know that it'll be 3 mm in 20 minute. Continuing the pattern, we can figure out that in 40 minutes the bacteria will be 81 mm.
The pattern: 10min - 3 20min - 9 30min - 27 40min - 81
9.16x10^6 = 9160000
8.05x10^8 =805000000
805000000
- 9160000

795840000
795840000 = 7.9584x10^8
