Answer:
C.
Step-by-step explanation:
G(x) exceeds f(x) from x = 0 to x = 3.
Then we see that f(x) is 11 at x = 4 and g(x) is 10 at x = 4, so there is an intersection between these 2 points.
After this f(x) far exceeds g(x).
Answer: You can do this!
Step-by-step explanation: For D. The x= -1 and the y= 1 for E same thing the x= 7 and the y= 1 so look for the 7 on the x-axes and the one on the y-axes get it. I believe that you got this!

Answer:
814.5 mg remain after 4 hours
Step-by-step explanation:
The multiplier of the original quantity is 1 -5% = 0.95 for each passing hour. The amount remaining after x hours is ...
y = 1000·0.95^x
For x=4, the amount remaining is ...
y = 1000·0.95^4 = 1000·0.81450625
y ≈ 814.5 . . . mg remain after 4 hours
