domain of f(x)=(3x)/(x^2-121)

domain

f (x) = \frac{3 x}{x ^{2} - 121}

x < - 11 or - 11 < x < 11 or x > 11

Interval Notation

(- \infty, - 11) \cup (- 11, 11) \cup (11, \infty)

Solution steps

Find undefined (singularity) points:

x = 11, x = - 11

The function domain

x < - 11 or - 11 < x < 11 or x > 11

\frac{6 x - 25}{- 5 x + 41}

f (x) = 4^{x} + 3

18 x

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

f (x) = 16 - 4 x^{2}
