Answer 1

Answer:

$\boxed{\bf x \geqslant 6}$

Step-by-step explanation:

Given:- g(x)=√(x - 4) and h(x) = 2x - 8

Find:- What're the restrictions on the domain of g•h.

______________________________

• $\bf g.h = \sqrt{(2x - 8) - 4}$
• $\bf g.h = \sqrt{2x - 12}$
• $\bf 2x - 12 \geqslant 0$
• $\bf 2x \geqslant 12$
• $\bf \cfrac{2x}{2} = \cfrac{12}{2}$
• $\bf x \geqslant 6$
