domain of f(x)=(sqrt(1-ln(x)))/(1-x^2)

domain

f (x) = \frac{1 - ln ( x )}{1 - x ^{2}}

0 < x < 1 or 1 < x \leq e

Interval Notation

(0, 1) \cup (1, e]

Solution steps

Find non-negative values for radicals:

0 < x \leq e

Find undefined (singularity) points:

x = 1, x = - 1

Combine real regions and undefined points for final function domain

0 < x < 1 or 1 < x \leq e
