Answer:

Last one

Step-by-step explanation:

The function f is:

● f (x)= √(4x+6)

The function g is:

● g(x) = √(4x-6)

Add them together:

● f+g (x)= √(4x+6 )+ √(4x-6)

Answer:

\large \boxed{{\sqrt{4x+6} + \sqrt{4x-6} }}

Step-by-step explanation:

f(x)=\sqrt{4x+6}

g(x)=\sqrt{4x-6}

(f+g)(x)

f(x)+g(x)

Add both functions.

(\sqrt{4x+6} )+ (\sqrt{4x-6} )
