Question

Problem 5. Find the domain of each function using the interval notation. \begin{align} (a) \ f(x) &= \frac{\sqrt{x-4}}{\sqrt{x-6}} \\ (b) \ f(x) &= \frac{x^2 - 9x}{x^2 - 81} \end{align}

          Problem 5. Find the domain of each function using the interval notation.
\begin{align*}
(a) \ f(x) &= \frac{\sqrt{x-4}}{\sqrt{x-6}} \\
(b) \ f(x) &= \frac{x^2 - 9x}{x^2 - 81}
\end{align*}

Problem 5. Find the domain of each function using the interval notation.

(a) f(x) = (√(x-4))/(√(x-6))

(b) f(x) = (x^2 - 9x)/(x^2 - 81)
