domain of 1/(log_{10)(x^2-4)}

domain

\frac{1}{lo g _{10} ( x ^{2} - 4 )}

x < - 5 or - 5 < x < - 2 or 2 < x < 5 or x > 5

Interval Notation

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

Solution steps

Find positive values for logs:

x < - 2 or x > 2

Find undefined (singularity) points:

x = 5, x = - 5

Combine real regions and undefined points for final function domain

x < - 5 or - 5 < x < - 2 or 2 < x < 5 or x > 5

f (x) = 3 x - 10

\frac{9 - x ^{2}}{x}

y = arccos (\frac{- x + 2}{2}) + \frac{π}{2}

\frac{3 x ^{2} - 10 x - 8}{x - 4}

- 4 x + 1

What is the domain of 1/(log_{10)(x^2-4)} ?
The domain of 1/(log_{10)(x^2-4)} is x<-sqrt(5)\lor-sqrt(5)<x<-2\lor 2<x<sqrt(5)\lor x>sqrt(5)
