Question

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

Answer 1

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

Explanation:

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

`g(x)=5+(2)/(x)` -----------------------(2)

Subtracting eq (2) from eq (1)

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

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

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