Solution

x < 4 or x > 4

+1

Interval Notation

(- \infty, 4) \cup (4, \infty)

Solution steps

Find undefined (singularity) points:

x = 4

The function domain

x < 4 or x > 4

Popular Examples

domain of (sqrt(5-2x))/(-7x)domain

\frac{5 - 2 x}{- 7 x}

domain of f(x)=9x-1620 domain

f (x) = 9 x - 1620

domain of-2/3 x-4 domain

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

domain of f(x)=5x^4-13 domain

f (x) = 5 x^{4} - 13

domain of f(x)= 2/(sqrt(-x^2+4x+5))domain

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