domain of (3x)/(x^2-25)

domain

\frac{3 x}{x ^{2} - 25}

x < - 5 or - 5 < x < 5 or x > 5

Interval Notation

(- \infty, - 5) \cup (- 5, 5) \cup (5, \infty)

Solution steps

Find undefined (singularity) points:

x = 5, x = - 5

The function domain

x < - 5 or - 5 < x < 5 or x > 5

f (x) = x - 3 + 6

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

f (x) = 14 x + 12

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

4 x^{2} + 7 x - 19
