Answer:

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

[tex]2\sqrt{6x}[/tex]

Step-by-step explanation:

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

f(x)=[tex]\sqrt{6x}+9[/tex]

and g(x)= [tex]\sqrt{6x}-9[/tex]

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

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

          =[tex]\sqrt{6x}+9+\sqrt{6x}-9[/tex]

          = [tex]2\sqrt{6x}[/tex]

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

[tex]2\sqrt{6x}[/tex]
