Question

F(x)= sqrt6x+9 , g(x) =sqrt 6x-9 find (f+g)(x)

Answer 1

The answer to the question

Answer 2

Value of (f+g)(x) is:

`2√(6x)`

Explanation:

We are given two functions f(x) and g(x) as:

f(x)=
`√(6x)+9`

and g(x)=
`√(6x)-9`

We have to find the value of (f+g)(x)

(f+g)(x)=f(x)+g(x)

=
`√(6x)+9+√(6x)-9`

=
`2√(6x)`

Hence, value of (f+g)(x) is:

`2√(6x)`
