Answer 2

Answer:

Answer will be - 3

Step-by-step explanation:

Domain of a function means selecting the values which makes the domain defined.

In this case,

If the denominator is zero then the function is not defined,

So for what value of

x

will the denominator be 0 ?

3 right ?

when

x

= 3 ,

f

(

x

)

=

1

0

which is not defined.

If you keep any other values except 3, your function is valid.

So, the domain is all values of the real line except 3.

x

= R -{3}
