domain of f(x)=(9x-5)/(x^2-9x+8)

domain

f (x) = \frac{9 x - 5}{x ^{2} - 9 x + 8}

x < 1 or 1 < x < 8 or x > 8

Interval Notation

(- \infty, 1) \cup (1, 8) \cup (8, \infty)

Solution steps

Find undefined (singularity) points:

x = 8, x = 1

The function domain

x < 1 or 1 < x < 8 or x > 8

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

y = 3 t^{2} - 2 t + 1

\frac{x ^{2} + 2 x - 8}{x ^{2} + 5 x + 4}

(6.8) (- 3.8) (- 6.8)

G (t) = \frac{( 3 t - 2 )}{( 3 - 4 t )}

What is the domain of f(x)=(9x-5)/(x^2-9x+8) ?
The domain of f(x)=(9x-5)/(x^2-9x+8) is x<1\lor 1<x<8\lor x>8
