Well the domain represents all the x values while range represents all the y values but i dont see a diagram so its would be diffcult a good example would be a parabola of a function like find domain of 1/x+2 to get domain set denominator eqaul to 0 since thats when a fraction is underfined when u do u get x cannot equal -2 thats the domain

Step-by-step explanation:
B
I don’t know how ybyybbyyb
The sample size, n required to produce a margin of error, M, in a probability proportion distribution is given by:

The above formular shows that the sample size is inversely proportional to the Margin of error.
Then we have:

where k is some constant.
Now suppose we decrease M by a factor of 3,


Therefore, if we decrease the Margin of error by a factor of 3, we need to increase the sample size by a factor of 9.
