is the equation this? \[\Large y = \sqrt{x-2}\]
or this?\[\Large y = \sqrt{x}-2\]

the 1st one

-2 ?

did you type in `sqrt(0-2)` or `sqrt(-2)` into your calculator?

yeah thats what it said when i did it in the calculator

so because of this error, we don't include x = 0 in the domain

i typed sqrt -2 not 0-2

which calculator are you using?

we wouldnt include any negative numbers in sqrt then

yes you cannot have negative numbers under the square root
eg: \(\Large \sqrt{-1}\) is not allowed

a scientific calculator

ok, what happens when you replace x with -1 instead of 0? what result do you get?

ok so i wot put any negatives then thx

i get -3

ok i see so only numbers 2 or more, no negatives

yep

if x = 2, then what is the value of y?

ok thank you and how would you sqrt 0 since 2-2 is 0

the square root of 0 is 0

nevermind i got it

ok one more: if x = 6, then what is the value of y?

thank you for helping me :)

it would be 4

oh srry it would be 2
