Question

Select the correct answer. Which function defines ( - 9)(r) ? f(s) = V + 11 g(t) = 5+ 1 A. + 16 + 6 ( - 3)(x) = V - B. ( - )(r) = VI c. (- 9)() = V + D. (- 9)(x) = 1 + 16 1 6 Reset

Answer 1

Given:

$\begin{gathered} f(x)=\sqrt[]{\frac{x}{8}}+11 \\ g(x)=5+\frac{2}{x} \end{gathered}$

Therefore,

$\begin{gathered} (f-g)(x)=f(x)-g(x) \\ \text{ =}\sqrt[]{\frac{x}{8}}+11-5-\frac{2}{x}=\sqrt[]{\frac{x}{8}}+6-\frac{2}{x} \end{gathered}$

Correct option is B.
