State the domain and the range i'm overthinking it so idk plz !

So the domain is the list of x, or input, values in an relation. They are the numbers that the arrows start at. In this case, the domain is {4,16}.

The range is the list of y, or output, values in an relation. They are the numbers that the arrows are pointing at. In this case, the range is {4,-2,2}.

Now for a relation to be a function, every input must only have 1 output. In this case, this relation is not a function because when x = 4, y = -2 and 2.

from the figure we get,

the x axis shows   the months and,

the y-axis shows the number of satisfied customer.

each line or each cell in upward direction (y-axis) shows 500.

the appropriate scale for the y - axis is: -

a = 2000 customers

b = 4000 customers

c = 6000 customers

d = 8000 customers

e = 10000 customers

f = 12000 customers

g = 14000 customers
