domain of f(x)=cos(1/x)

domain

f (x) = cos (\frac{1}{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

- 4 x + 5

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

f (x) = x^{2} + 5 x + 4

x^{3} - 12 x + 1

y = 7

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