domain of f(x,y)= 1/2 x-6/x

domain

f (x, y) = \frac{1}{2} x - \frac{6}{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) = 21 - x

f (x) = 1 - x - 1

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

f (x) = 8 x^{2} - 7 x + 9

f (x) = 2 - 2 - x

What is the domain of f(x,y)= 1/2 x-6/x ?
The domain of f(x,y)= 1/2 x-6/x is x<0\lor x>0
