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

domain

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

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

Solution steps

Find undefined (singularity) points:

x = 4, x = 0

The function domain

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

f (x) = 5 y + 4 = (x + 3)^{2} + \frac{1}{2}

\frac{36 - x ^{2}}{x + 2}

f (x) = 3 x - 4

f (x) = \frac{2 x - 4}{3}

\frac{7}{x}

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