Answer 1

it depends upon the function

Answer 2

how about this?
y = 3 - 2x
what is the domain and range?

Answer 3

start putting values in x from -infinity to + infinity and see the values of y,

Answer 4

as the given function is a linear function so its domain and range is

domain = set of real numbers
range = set of real numbers

Answer 5

i don't understand.. sorry!

Answer 6

more precisely

domain = -infinity < x < +infinity
range = +infinity < y < - infinity

Answer 7

ahh.. eh, how about this, y = -5?

Answer 8

domain = -infinity < x < +infinity
range = y = -5

Answer 9

explain it to me.. please..

Answer 10

if we plot y = -5 we get
