Weight of 1 c
3 c = 2.25 - empty bucket
3 c = 2.25 - 0.75
3 c = 1.5
c = 1.5/3 =1/2
Jug Weigh = (1/2)x +0.75
Answer:
Step-by-step explanation:
a) The domain is R- all real numbers.
b) The domain is R- all real numbers.
c) we need

So the domain is R\{-2, 2}
d)
we need

So the domain is R\{-2, 1}
e)
we need: x-1>0 or x> 1
So the domain is (1,+∞)
The third answer option is correct. sqrt(x) = x^(1/2). So sqrt(121) = 121^(1/2).
