domain of (x^2-36)/(x^2-9x+8)

domain

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

f (x) = 4 x^{2} + 1

f (x) = - sin^{2} (x) + 1

f (x) = \frac{2 x + 8}{3 x + 18}

1 0^{x}

f (x) = \frac{1 - x - 4}{x ^{2} - 1}

What is the domain of (x^2-36)/(x^2-9x+8) ?
The domain of (x^2-36)/(x^2-9x+8) is x<1\lor 1<x<8\lor x>8
