domain of (2x-4)/(x^2-6x+8)

domain

\frac{2 x - 4}{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

f (x) = 3^{x + 1} - 1

f (x) = - 625 - y^{4}

y = 2 x - 5

f (x) = - x^{2} + 4 x + 3

\frac{( 2 x ^{2} + 6 )}{2 x ^{2} + 3 x - 2}

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