If it is the domain is all the numbers that make .5x-5 positive or 0
Mertsj
  • Mertsj
\[\frac{1}{2}x-5\ge0\]
Mertsj
  • Mertsj
\[x \ge10\]
Mertsj
  • Mertsj
That is the domain.

  • Mertsj
\[f(20)=\sqrt{.5(20)-5}=\sqrt{5}\]
Mertsj
  • Mertsj
\[f(16)=\sqrt{.5(16)-5}=\sqrt{8-5}=\sqrt{3}\]
Mertsj
  • Mertsj
\[f(12)=\sqrt{.5(12)-5}=\sqrt{6-5}=\sqrt{1}=1\]

  • Mertsj
\[f(14)=\sqrt{.5(14)-5}=\sqrt{7-5}=\sqrt{2}\]

You know, it would really be nice if, when you ask for help, and someone helps you that you would have the common courtesy to read what they wrote.
