Answer:

Step-by-step explanation:

Solve to find the values of  

x

that make  

√ x − 1

defined.

Tap for fewer steps...

Set up the equation to solve for  x .

x − 1 ≥ 0

Add  1  to both sides of the inequality.

x ≥ 1

The domain is all values of  x

that make the expression defined.

[ 1 , ∞ ) { x | x ≥ 1 }

The range of an even indexed radical starts at its starting point  

( 1 , 0 )

and extends to infinity.

[ 0 , ∞ ) { y |y ≥ 0 }

Determine the domain and range.

Domain:  

[ 1 , ∞ ) , { x | x ≥ 1 }

Range:  

[ 0 , ∞ ) , { y | y ≥ 0 }
