Answer:
Well for Part A-
List the temperatures from least to greatest; anything under 0 degrees is the lowest.
-6.1
-2.5
-0.4
3.4
And for Part B-
You can use a number line to order the temperatures because it's a good way to sort which ones are the lowest and highest easily.
The answer to your question is A.
answer: 3.6
Actually, there would be no solution because the w's cancel out so that leaves -6=-9 and that is not true.
F(x)=x/(3x+2)
f(a+h)=(a+h)/(3a+3h+2)
