Find $( f + g ) ( x )$
A) $6 x + 6$
B) 6
C) $6 \sqrt { x - 6 }$
D) $6 \sqrt { 2 x - 12 }$

Question

Quizplus · Accepted Answer

To find $(f + g)(x)$, you add the functions $f(x)$ and $g(x)$ together: $4\sqrt{x-6} + 2\sqrt{x-6} = 6\sqrt{x-6}$.

Perform the Requested Operation on the Given Function f(x)=4x−6,g(x)=2x−6f ( x ) = 4 \sqrt { x - 6 } , g ( x ) = 2 \sqrt { x - 6 }f(x)=4x−6​,g(x)=2x−6​
