domain of ln(1/(x^2-4))

domain

ln (\frac{1}{x ^{2} - 4})

x < - 2 or x > 2

Solution steps

Find positive values for logs:

x < - 2 or x > 2

Find undefined (singularity) points:

x = 2, x = - 2

Combine real regions and undefined points for final function domain

x < - 2 or x > 2

\frac{1}{6.1 x - 3.5 x ^{2}}

\frac{x - 3}{x + 1}

x^{2} + 8 x + 11

- 2^{- x}

F (x) = 4 cos (\frac{1}{x})
