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

domain

f (x) = \frac{1}{x} + \frac{x}{2} + 1

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) = \frac{x + 1}{x ^{3} - 9 x}

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

f (x) = \frac{3}{2 x - 8}

f (x) = \frac{( x + 2 )}{( x ^{2} - 1 )}

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

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