domain of f(x)= 5/(5/x)

domain

f (x) = \frac{5}{\frac{5}{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) = 2 x^{3} - 3 x^{2} + x

(- 6.4) (7.6)

1 - x^{2} + x^{2} - 1

y = \frac{2 x - 4}{3}

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

What is the domain of f(x)= 5/(5/x) ?
The domain of f(x)= 5/(5/x) is x<0\lor x>0
