domain

\frac{13}{13 - x}

x < 13 or x > 13

Interval Notation

(- \infty, 13) \cup (13, \infty)

Solution steps

Find undefined (singularity) points:

x = 13

The function domain

x < 13 or x > 13

y = ln (\frac{- x + 3}{2})

f (x) = \frac{4}{( 2 x - 8 )}

\frac{7 x}{5 x - 4}

\frac{4}{- 6 x ^{2} - 5 x - 1}

∣ x - 5 ∣
