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

domain

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

7 x^{2} + 3 x - 1

f (x) = \frac{x - 2}{2 x ^{2} + x - 10}

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

\frac{2}{x ^{2} - 2 x - 35}

f (x) = ln (x + 5 - 1)

What is the domain of (x^2-12)/(2x) ?
The domain of (x^2-12)/(2x) is x<0\lor x>0
