domain of f(x)=log_{10}((x-2)/(x^2-5))

domain

- 5 < x < 2 or x > 5

Interval Notation

(- 5, 2) \cup (5, \infty)

Solution steps

Find positive values for logs:

- 5 < x < 2 or x > 5

Find undefined (singularity) points:

x = 5, x = - 5

Combine real regions and undefined points for final function domain

- 5 < x < 2 or x > 5

What is the domain of f(x)=log_{10}((x-2)/(x^2-5)) ?
The domain of f(x)=log_{10}((x-2)/(x^2-5)) is -sqrt(5)<x<2\lor x>sqrt(5)
