Answer:


\boxed{\bf x \geqslant 6}

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 = √((2x - 8) - 4)

  • \bf g.h = √(2x - 12)

  • \bf 2x - 12 \geqslant 0

  • \bf 2x \geqslant 12

  • \bf \cfrac{2x}{2} = \cfrac{12}{2}

  • \bf x \geqslant 6
