domain of f(x)=(x-1)/(2x)

domain

f (x) = \frac{x - 1}{2 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 - 3} - 5

f (x) = lo g_{7} (2 x + 4)

f (x) = sin (x) - 5

f (t) = \frac{1}{t - 2}

f (x) = y^{4} - 8 y^{2} + 4 x^{2} - 9 = 0

What is the domain of f(x)=(x-1)/(2x) ?
The domain of f(x)=(x-1)/(2x) is x<0\lor x>0
