domain of f(x)=(x^2-x-2)/(x^2-6x+8)

domain

f (x) = \frac{x ^{2} - x - 2}{x ^{2} - 6 x + 8}

x < 2 or 2 < x < 4 or x > 4

Interval Notation

(- \infty, 2) \cup (2, 4) \cup (4, \infty)

Solution steps

Find undefined (singularity) points:

x = 4, x = 2

The function domain

x < 2 or 2 < x < 4 or x > 4

1 - 2 + x

y = \frac{2 x ^{2} - 6 + 4}{- 3 x - 5}

∣ x + 3 ∣

2^{x - 1} - 2

f (x) = 7 - 9 - 3 x

What is the domain of f(x)=(x^2-x-2)/(x^2-6x+8) ?
The domain of f(x)=(x^2-x-2)/(x^2-6x+8) is x<2\lor 2<x<4\lor x>4
