Answer:
B [tex](f-g) (x)= \sqrt{\frac{x} {8} } -\frac{2}{x} +6[/tex]
Step-by-step explanation:
[tex]f(x)= \sqrt{\frac{x} {8} } +11[/tex] ------------------(1)
[tex]g(x)=5+\frac{2}{x}[/tex] -----------------------(2)
Subtracting eq (2) from eq (1)
[tex]f-g= \sqrt{\frac{x} {8} } +11 - (5+\frac{2}{x} )[/tex]
[tex]f-g= \sqrt{\frac{x} {8} } +11 - 5 -\frac{2}{x}[/tex]
[tex]f-g= \sqrt{\frac{x} {8} } -\frac{2}{x} +6[/tex]
