The points represented are:
The domain is the set of all the inputs, i.e. the set composed by the x-coordinates of these points.
The range is the set of all the outputs, i.e. the set composed by the y-coordinates of these points.
This relation is a function, because you never map two outputs for the same input (i.e. you don't have two points with the same x-coordinate, but different y-coordinates).

Answer:
341.95≤x≤358.95
Step-by-step explanation:
The confidence interval formula is expressed as;
CI = xbar±(z×s/√n)
xbar is the mean sample
s is the standard deviation
z is the z score at 95% confidence interval
n is the sample size
xbar = 350kg
z = 1.96
s = 25kg
n = 30
Substitute
CI = 350±(1.96×25/√30)
CI = 350±(1.96×4.564)
CI = 350±(8.946)
CI = (350-8.946, 350+8.946)
CI = (341.05, 358.95)
Hence the 95% confidence interval for how much food the elephant eats us 341.95≤x≤358.95
