Given the function
[tex]f(x)=\sqrt{x+5};g(x)=\frac{2}{x}[/tex]
We are asked to find (fog)(x)
Explanation
In mathematics, function composition is an operation ∘ that takes two functions f and g, and produces a function h = g ∘ f such that h(x) = g(f(x)). In this operation, the function g is applied to the result of applying the function f to x.
[tex]f(g(x)=\sqrt{\frac{2}{x}+5}[/tex]
Answer: Option A
