Question

What is the excluded value for the radical function?

Answer 1

where

sqrt(x)

x<0

Answer 2

4x+5<0 are excluded

Answer 3

so 4x+5 are the excluded values?

Answer 4

anything that makes that less than 0 is exluded

Answer 5

WHY? cuzz if you look as sqrt(x) as the inverse of x^2


then there is really no number less than 0 which will satisfy sqrt(-x)

Answer 6

*AT not as lol

Answer 7

DO you think Gengar cares about medals :P

Answer 8

@timo86m Ok, so then it is the right answer..?

Answer 9

I feed on your dreams ;) Dream eater :D

Answer 10

@timo86m It's a nice day to troll some newbies, isn't it?

Answer 11

I am not trolling!

Answer 12

think about what sqrt of x means @carolinamarissa ?

It means what 2 same numbers multiply together to get x?

like sqrt of 9= 3 cuz 3 and 3 multiply together to make 9.

in other words 3*3=9 sqrt 9=3 however if you have sqrt -9 then no number exists where you can do that.

infact no number exist for any negitive number.

so you got

4x+5

4x+5 < 0 as soon as left hand side gets under zero then you are breaking the rules so therefore we solve.

4x < -5
x< -5/4 seems to be the answer. Unless I id a careless mistake.

Answer 13

@timo86m thank you so much! :)

Answer 14

De nada
