Question

What is the range and domain

Answer 1

Range is always talking about the y values, and domain is always talking about the x values

Answer 2

How do I tell the difference

Answer 3

range = how far Up and Down it goes
domain = how far Left and Right it goes

Answer 4

the arrow pointing forwards seem to indicate ever going, or \(\Large \infty\)

Answer 5

Range : -3 -3 -5
Domaine -1 -2 -3 -4 ?

Answer 6

Now im super confused

Answer 7

so....how far UP it goes?

Answer 8

Which one?

Answer 9

both graphs... both graphs I'd think are part of the same equation

Answer 10

oh ok well it goes up to 2

Answer 11

yeap and down.... since the arrow is pointing downwards, I'd think it goes to \(\Large \infty\) thus the range then would be \(\Large [2, -\infty)\)

Answer 12

so the domain would be that symbol and the range would be what you just put?

Answer 13

well... the domain is how far left and right it goes

based on the arrow pointing, I'd think it goes to -> infinity \(\Large \infty\) to the right

but on left, it has a limit

Answer 14

which is 5 right?

Answer 15

it seems to get to well... is not 5 or +5 is not positive 5
is negative 5 notice the graph
BUT

notice the HOLE there, it means it doesn't really touch it

when the domain includes a number limit but doesn't touch it, you'd use a ( instead of a [

Answer 16

like in the case before, the domain was \(\Large [2, -\infty)\) meaning
"2" is part of it, it touches it BUT infinity, is never touched... since infinite is not really a number, just a concept

Answer 17

hmm the range I mean, was \(\Large [2, -\infty)\)

Answer 18

so the domain would be - infinity -5?

Answer 19

hmm well... you got the left on the right and the right on the left
