domain of f(x)=(-4)/x+1

domain

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

\frac{3}{x - 2} + 4

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

36 x^{2} - 2 x^{3}

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

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

What is the domain of f(x)=(-4)/x+1 ?
The domain of f(x)=(-4)/x+1 is x<0\lor x>0
