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 }
