domain of f(x)=sqrt((x-1)/(x^2-5x+6))

domain

1 \leq x < 2 or x > 3

Interval Notation

Solution steps

Find non-negative values for radicals:

1 \leq x < 2 or x > 3

Find undefined (singularity) points:

x = 3, x = 2

Combine real regions and undefined points for final function domain

1 \leq x < 2 or x > 3

What is the domain of f(x)=sqrt((x-1)/(x^2-5x+6)) ?
The domain of f(x)=sqrt((x-1)/(x^2-5x+6)) is 1<= x<2\lor x>3
