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

Solution

domain

f (x) = 1 + \frac{4}{x}

Solution

x < 0 or x > 0

+1

Interval Notation

(- \infty, 0) \cup (0, \infty)

Solution steps

Find undefined (singularity) points:

x = 0

The function domain

x < 0 or x > 0

Popular Examples

extreme f(x)=x^4+16x^3-2 extreme points

f (x) = x^{4} + 16 x^{3} - 2

intercepts of 3x+6 intercepts

3 x + 6

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

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

range of f(x)=(sqrt(2+x))/(x-5)range

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

range of f(x)=sqrt(2x-3)range

f (x) = 2 x - 3
