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

domain

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

x < 0 or 0 < x < 4 or x > 4

Interval Notation

(- \infty, 0) \cup (0, 4) \cup (4, \infty)

Solution steps

Find undefined (singularity) points:

x = 4, x = 0

The function domain

x < 0 or 0 < x < 4 or x > 4

\frac{3 x - 1}{2 x + 5}

m = 1, (0, 3)

(x - 8)^{2}

2.5 cos (4 x)

f (x) = cos (\frac{1}{2} x - \frac{π}{4})

What is the domain of f(x)= 4/(x^2-4x) ?
The domain of f(x)= 4/(x^2-4x) is x<0\lor 0<x<4\lor x>4
