Answer:

Step-by-step explanation:
Given:
Given polynomial function is.

Hours 
We need to find the concentration of the antibiotic after 3 hours.
Solution:
Rewrite the given polynomial function as.

Substitute
in given polynomial function.





Therefore, the concentration of the antibiotic after 3 hours
.
74/100=34/n
cross multiply proportion
74n=3400
then divide both sides by 74
n= ~46
1: (-3)2= -6
2: (-6)4= -24
3: (-1)8= -8
Well you change 6 and 3 5ths into a improper fraction= 33/5 and that equals -1/5
Hey there! :)
