domain of f(x)=log_{10}((x+2)/(x-4))

domain

f (x) = lo g_{10} (\frac{x + 2}{x - 4})

x < - 2 or x > 4

Interval Notation

(- \infty, - 2) \cup (4, \infty)

Solution steps

Find positive values for logs:

x < - 2 or x > 4

Find undefined (singularity) points:

x = 4

Combine real regions and undefined points for final function domain

x < - 2 or x > 4

5 x^{2} + x - 2

f (x) = 1 - y + 1

\frac{( x - 7 )}{( x + 4 )}

f (x) = \frac{x + 6}{x ^{2} + x - 30}

ln (x^{2} + 25)

What is the domain of f(x)=log_{10}((x+2)/(x-4)) ?
The domain of f(x)=log_{10}((x+2)/(x-4)) is x<-2\lor x>4
