domain of (1/(x-7))+(1/x-9)

domain

(\frac{1}{x - 7}) + (\frac{1}{x} - 9)

x < 0 or 0 < x < 7 or x > 7

Interval Notation

(- \infty, 0) \cup (0, 7) \cup (7, \infty)

Solution steps

Find undefined (singularity) points:

x = 7, x = 0

The function domain

x < 0 or 0 < x < 7 or x > 7

f (x) = 25 - 5^{x}

f (x) = \frac{x ^{3}}{( x - 1 ) ^{2}}

f (x) = 12 x - 2148

\frac{x + 9}{x - 4}

\frac{5 - 2 x}{- 7 x}

What is the domain of (1/(x-7))+(1/x-9) ?
The domain of (1/(x-7))+(1/x-9) is x<0\lor 0<x<7\lor x>7
