QuestionComplete the table using the function $f(x)=\sqrt{x-4}$. Simplify answers or mark as "Not a real number" if needed.

Studdy Solution
The square root of81 is9. So, $f(85)=9$.
The completed table is\begin{tabular}{|c|c|} \hline$x$ & $f(x)$ \\ \hline0 & Not a real number \\ \hline &0 \\ \hline13 &3 \\ \hline85 &9 \\ \hline\end{tabular}
