domain of (12)/(x^2-25)-3

domain

\frac{12}{x ^{2} - 25} - 3

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 + 1) (x + 1 - 1) (x + 1 - 2)

y^{3} + 3 x = 6

\frac{x ^{2} - 1}{5 x ^{2} + 5 x}

f (x) = \frac{x ^{2}}{x ^{2} - x - 6}

\frac{x ^{2} - 4 x - 8}{[ - 3.6 ]}
