domain of y=sqrt((2x+1)/(x-1))

domain

y = \frac{2 x + 1}{x - 1}

x \leq - \frac{1}{2} or x > 1

Interval Notation

(- \infty, - \frac{1}{2}] \cup (1, \infty)

Solution steps

Find non-negative values for radicals:

x \leq - \frac{1}{2} or x > 1

Find undefined (singularity) points:

x = 1

Combine real regions and undefined points for final function domain

x \leq - \frac{1}{2} or x > 1

What is the domain of y=sqrt((2x+1)/(x-1)) ?
The domain of y=sqrt((2x+1)/(x-1)) is x<=-1/2 \lor x>1
