domain of-ln((100-x)/(9x))

domain

- ln (\frac{100 - x}{9 x})

0 < x < 100

Interval Notation

(0, 100)

Solution steps

Find positive values for logs:

0 < x < 100

Find undefined (singularity) points:

x = 0

Combine real regions and undefined points for final function domain

0 < x < 100

ln (x - 1) + ln (y)

ln (x^{2} (y))

ln (\frac{121.306}{125})

ln (4) + 3 ln (x) + 5 ln (x^{2} + 10)

ln (6) - 3 ln (a) + ln (b)

What is the domain of-ln((100-x)/(9x)) ?
The domain of-ln((100-x)/(9x)) is 0<x<100
