For functions, x’s can’t repeat, so looking at the first problem, C is the only one where the first number in each coordinate (x,y) doesn’t repeat.
For the second, x = -2 means that no x is always -2 matter which y you would look at. So x’s repeat and it forms a vertical line. So it is not a function
Answer:
The correct option is;
e. 2500
Step-by-step explanation:
The formula for sample size is given by the following formula;

At 95%, z = 1.96
ε = Margin of error = 0.02 = 2%
Finding the sample size, n, given only the margin of error is by the following formula;
Margin of error = 100/√n
Therefore, we have;
2 = 100/√n
√n = 100/2 = 50
n = 50² = 2500
Therefore, the correct option is e. 2500.
