Step 1 :The function given is \(f(x)=\frac{x+5}{x^{2}-16}\).
Step 2 :The domain of a function is the set of all possible input values (x-values) which will output real numbers.
Step 3 :In this case, the function is a rational function, and the denominator cannot be zero.
Step 4 :Therefore, we need to find the values of x that make the denominator zero and exclude them from the domain.
Step 5 :The denominator is \(x^{2}-16\), which can be factored into \((x-4)(x+4)\).
Step 6 :Therefore, the values of x that make the denominator zero are 4 and -4.
Step 7 :So, the domain of the function is all real numbers except 4 and -4.
Step 8 :Final Answer: The correct domain is \(\boxed{(-\infty,-4) \text{ or } (-4,4) \text{ or } (4, \infty)}\).
