Chapter 10.5, Problem 5P

Find the domain of each function.

$y=\sqrt{x-9}$

To determine

To find: the domain of function.

Answer to Problem 5P

The domain of function is $x\ge 9$ .

Explanation of Solution

Given information:

The function is $y=\sqrt{x-9}$ .

Calculation: to find the domain of the function, the function is defined for all the $x$ which,

  $\begin{array}{l}x-9\ge 0\\ x\ge 9\text{ [simplify]}\end{array}$

Thus, the domain of the function is $x\ge 9$ .
