Question

@waterineyes

Answer 1

can you please explain how to solve this. Anyway got 100% in my exam last Saturday!

Answer 2

-3, because it will divide by zer

Answer 3

I dont understand why x+3 will be 0 here why not x+4?

Answer 4

I dont understand why x+3 will be 0 here why not x+4?@AugustinusSextus

Answer 5

for what value of x \[\frac{x+4}{x+3}\] suppose you put -4 then it would be \[\frac{0}{-1}=0\] but suppose you put -3 \[\frac{1}{0}=\text{ undefined }\]

Answer 6

I am so sorry @waterineyes

Answer 7

What is the question can you explain it here..

Answer 8

Yeah as I can't see it, it is undefined..

Ha ha ha..

Answer 9

For what value(s) is the statement x+4 undifined?
x+3

Answer 10

Idont really know how to use drawing here though

Answer 11

When a fraction gets undefined?/

When its denominator becomes 0..

So:

x + 3 = 0 (this condition we have to avoid)

So \(x \ne -3\)..

Answer 12

It's a theory, remember it , you put all the time The denominator \[\neq 0\]
In this case:
\[x +3 \neq 0\]
\[x \neq -3\]

Answer 13

How about when the numerator is equal to 0 how you call that?@waterineyes

Answer 14

Which grade you are in @nia_maepenix

Answer 15

@waterineyes first year

Answer 16

Ah it's easy just it's all 0

Answer 17

If numerator is 0 then the value is 0 and not, not defined..

Answer 18

Have you studied about functions range domain etc..??

Answer 19

\[\large \frac{0}{1} = 0\]

\[\large \frac{1}{0} = \color{green}{Undefined}\]

Answer 20

\[o \div x+3\]

Answer 21

So, you are allowed to make numerator 0 but denominator should be not equal to 0..

Answer 22

so any number divided by zero is equal to zero?

Answer 23

\[\large \frac{0}{x+3} = 0\]

Answer 24

If x is different than -3, so the value will be 0, if x= -3 it's undefined

Answer 25

0 is divided by any number is 0 @nia_maepenix

Answer 26

@waterineyes thanks a lot. I understand it now Dear

Answer 27

Here you are dividing 0 with x + 3 so :

0 divided by any number is 0 and any number divided by 0 is undefined..

Answer 28

Welcome dear..
