Question

F(x)= 3/x+5

Answer 1

What is the question ?

Answer 2

Determine the domain of each function

Answer 3

all real numbers except x = 0

Answer 4

So I substitute x to 0

Answer 5

when u put x =0 u will gget infinity

Answer 6

so all real numbers are domain but\[x \neq0\]

Answer 7

It's just 0??

Answer 8

no.. just not 0.. except 0 every number is in the domain

Answer 9

So it's 3/5

Answer 10

do you know what domain is?

Answer 11

It's then x value right

Answer 12

domain is the possible values of x for which you can get some definite answer..

Answer 13

so all real number means
1,-1,2,-2,3,-3 and so on .. just not 0
because when u put 0 u will get infinity so 0 not included. so every number in arithmetic is in the domain of this equation except 0

Answer 14

But negative numbers aren't real numbers or are they...

Answer 15

i think they are.

Answer 16

Ok so wat do I do

Answer 17

@nubeer are you helping jay ?

Answer 18

I don't get this

Answer 19

yes i am trying if u can see..
u can write all real numbers \[x \neq0\]
or
\[[-\infty , 0) (0,\infty]\]

Answer 20

Oh ok that makes sense

Answer 21

Thank you

Answer 22

you are welcome.

Answer 23

3/x+5= f(x)

we knw 3/0 is not defined...so

x + 5 not equal 0

x not equal 5

so...Domian = R-{5}

Answer 24

@jay847 u got it ?

Answer 25

x not equal -5 *
