Question

Hi, does anyone know what the range could be for an equation such as y= 0x + 3? Thanks!

Answer 1

The range is the possible set of values for the function y. So, what values for y could you possibly get with any value for x?

Answer 2

Well you'd only get 3

Answer 3

So, the range is 3 then :)

Answer 4

so then would I write {y E R | y = 3 } or something else? Or do I just write {y E R } ?

Answer 5

The range is indeed 3.

Answer 6

well, the first statement is redundant, and the second statement is incorrect

Answer 7

you'd want
{y: y=3}

Answer 8

oh, so i shouldn't include the "member of the reals" part?

Answer 9

3 is a member of the reals, but saying that y is a member of the reals AND y is 3 is redundant, and can be simplified to y=3

Answer 10

it's for the same reason you wouldn't want y∈R AND y∈Q AND y∈Z AND y∈N AND y∈{3}, because y is simply 3

Answer 11

wait, that last part is bad

Answer 12

I mean to say, {y: y∈R AND y∈Q AND y∈Z AND y∈N AND y∈{3}}

Answer 13

Oh okay. So simply {y=3} would be enough and would make sense as well, right?

Answer 14

I'd write {y: y=3}, or {y | y=3}

Answer 15

Oh okay then, thanks!

Answer 16

it's probably simpler to say y={3} actually. Sorry for changing what I said so many times >.<
