domain of (x^2-49)/(x^2-81)

domain

\frac{x ^{2} - 49}{x ^{2} - 81}

x < - 9 or - 9 < x < 9 or x > 9

Interval Notation

(- \infty, - 9) \cup (- 9, 9) \cup (9, \infty)

Solution steps

Find undefined (singularity) points:

x = 9, x = - 9

The function domain

x < - 9 or - 9 < x < 9 or x > 9

\frac{5 x}{7 x - 1}

ln (1 - ln (x))

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

\frac{x + 6}{x - 7}

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