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

domain

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

\frac{4 x ^{2}}{x ^{2} - 9}

\frac{3 x + 12}{- 12 x + 4}

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

f (x) = x^{2} - 8 x + 14

f (x) = x^{2} - 8 x + 15

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