domain of f(x)=(8-x)/(x^2-5x)

domain

f (x) = \frac{8 - x}{x ^{2} - 5 x}

x < 0 or 0 < x < 5 or x > 5

Interval Notation

(- \infty, 0) \cup (0, 5) \cup (5, \infty)

Solution steps

Find undefined (singularity) points:

x = 5, x = 0

The function domain

x < 0 or 0 < x < 5 or x > 5

f (x) = 3 x - 7

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

(- \frac{11}{3}, 0), (0, \frac{11}{2})

f (x) = 4 x^{2} - 16 x + 9

f (x) = \frac{∣ x - 5 ∣}{x - 5}

What is the domain of f(x)=(8-x)/(x^2-5x) ?
The domain of f(x)=(8-x)/(x^2-5x) is x<0\lor 0<x<5\lor x>5
