Find the Domain and Range f(x) = square root of x-10

$f (x) = \sqrt{x - 10}$

Step 1

Set the radicand in $\sqrt{x - 10}$ greater than or equal to $0$ to find where the expression is defined.

$x - 10 \geq 0$

Step 2

Add $10$ to both sides of the inequality.

$x \geq 10$

Step 3

The domain is all values of $x$ that make the expression defined.

Interval Notation:

$[10, \infty)$

Set-Builder Notation:

${x | x \geq 10}$

Step 4

The range is the set of all valid $y$ values. Use the graph to find the range.

Interval Notation:

$[0, \infty)$

Set-Builder Notation:

${y | y \geq 0}$

Step 5

Determine the domain and range.

Domain: $[10, \infty), {x | x \geq 10}$

Range: $[0, \infty), {y | y \geq 0}$
