The function f(x) = 3.8 x + 1, represents the amount of grapes in a barrel after x seconds.  Barry needs to fill the 100 gallon bucket.  What is an appropriate domain for the function?

caozeyuan · Answer

ok so x cannot be smaller than 0

caozeyuan · Answer

and it has to be smaller than (100-1)/3.8

anonymous · Answer

so would it be 0 < x < 44433.3, the total amount of water that will be in the pool

caozeyuan · Answer

I don't understand what you are talking about

caozeyuan · Answer

the bigger number is impossible

anonymous · Answer

caozeyuan · Answer

that would be very helpful

anonymous · Answer

a . 0 < x < 44433.3, the total amount of water that will be in the pool
b.0<x\le44433.3, the amount of time it takes to fill the pool
c . 0 < x < 200000, the total amount of water in the pool
d . x < 200000, the amount of time it takes to fill the pool

caozeyuan · Answer
