domain of f(x)=(7x+63)/(9x)

domain

f (x) = \frac{7 x + 63}{9 x}

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

f (x) = 2 x - 1 + 3

3^{2 x - 1}

- 5 sin (29 (x - 3)) - 8

f (x) = \frac{3 x - 4}{x + 2}

x^{\frac{2}{3}} - x^{\frac{1}{3}}

What is the domain of f(x)=(7x+63)/(9x) ?
The domain of f(x)=(7x+63)/(9x) is x<0\lor x>0
