domain of (100)/(x^2)-9

domain

\frac{100}{x ^{2}} - 9

x < 0 or x > 0

Interval Notation

(- \infty, 0) \cup (0, \infty)

Solution steps

Find undefined (singularity) points:

x = 0

The function domain

x < 0 or x > 0

r (x) = \frac{x ^{2} + 5 x}{25 - x ^{2}}

- e^{x} - 6

1 - cy

f (x) = \frac{x + 3}{x ^{2} - 36}

f (x) = 14 - x + 14 + x
