domain of f(x)= 7/(x^2-4x)

domain

f (x) = \frac{7}{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

f (x) = 3 x^{2} - 12 x + 13

ln (x - 3) + 1

f (x) = \frac{3 x ^{2} + 15 x}{x ^{2} + 1}

\frac{x ^{2}}{( 1 - x ^{2} )}

f (x) = 4 15 x - 3

What is the domain of f(x)= 7/(x^2-4x) ?
The domain of f(x)= 7/(x^2-4x) is x<0\lor 0<x<4\lor x>4
