Answer:


Step-by-step explanation:

Take a look at the function f(x) = √(x-1).  The input to the square root function MUST be ≥ 0.  Write and solve the inequality x-1 ≥ 0:  

Adding 1 to both sides, we get x ≥ 1, or [1,infinity).  This is the domain, the set of numbers for which f(x) is defined.

The smallest value that f(x) = √(x-1) can take on is 0 (at x=1).  Thus, the range is y≥0. or [0,infinity).  The range is the set of all possible output values of the function with which we are concerned.
