Question

Need some help, ASAP if possible. TY in advance!

Answer 1

Answer:

B         $(f-g) (x)= \sqrt{\frac{x} {8} } -\frac{2}{x} +6$

Step-by-step explanation:

$f(x)= \sqrt{\frac{x} {8} } +11$ ------------------(1)

$g(x)=5+\frac{2}{x}$ -----------------------(2)

Subtracting eq (2) from eq (1)

$f-g= \sqrt{\frac{x} {8} } +11 - (5+\frac{2}{x} )$

$f-g= \sqrt{\frac{x} {8} } +11 - 5 -\frac{2}{x}$

$f-g= \sqrt{\frac{x} {8} } -\frac{2}{x} +6$
