User the function $f(x)=\log _{5}(x-3)-2$ to answer the following:
(a) Determine the equation of the asymptote of $f(x)$.
(b) Determine the domain of $f(x)$ in interval notation.
(c) Determine the range of $f(x)$ in interval notation.
The range of \(f(x)\) in interval notation is \(\boxed{(-\infty, \infty)}\)
Step 1 :Set the argument of the logarithm equal to zero: \(x-3=0\)
Step 2 :Solve for \(x\) to get \(x=3\)
Step 3 :\(\boxed{x=3}\) is the equation of the asymptote of \(f(x)\)
Step 4 :Set \(x-3>0\) to find the domain of \(f(x)\)
Step 5 :Solve for \(x\) to get \(x>3\)
Step 6 :The domain of \(f(x)\) in interval notation is \(\boxed{(3, \infty)}\)
Step 7 :Since the base of the logarithm is greater than 1, the function is increasing for all values in its domain
Step 8 :Therefore, the function will take on all real number values
Step 9 :The range of \(f(x)\) in interval notation is \(\boxed{(-\infty, \infty)}\)
