Let f(x) = √(x-1) and g(x) = 1/(x-1). Find the domain for f and g, and the range of f.
Added by Kelly A.
Step 1
In this case, the square root function is defined for non-negative values. Therefore, the expression inside the square root, x-1, must be greater than or equal to 0. x - 1 ≥ 0 x ≥ 1 So, the domain of f(x) is all real numbers greater than or equal to 1, or in Show more…
