domain of f(x)=(x+1)/(x^2-6x+5)

domain

f (x) = \frac{x + 1}{x ^{2} - 6 x + 5}

x < 1 or 1 < x < 5 or x > 5

Interval Notation

(- \infty, 1) \cup (1, 5) \cup (5, \infty)

Solution steps

Find undefined (singularity) points:

x = 5, x = 1

The function domain

x < 1 or 1 < x < 5 or x > 5

x^{2} - 7 x + 12

\frac{6 x - 7}{5 x + 4}

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

f (x) = 2 t + t^{2}

ln (x^{2} + 5 x - 6)

What is the domain of f(x)=(x+1)/(x^2-6x+5) ?
The domain of f(x)=(x+1)/(x^2-6x+5) is x<1\lor 1<x<5\lor x>5
