domain of f(x)=(x+1)/(x^2-6x+8)

domain

f (x) = \frac{x + 1}{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

x^{2} - 3

f (x) = 2 + 4 sin (3 x + \frac{π}{2})

3 x - 5 + 7

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

3 y + 4 x = 12

What is the domain of f(x)=(x+1)/(x^2-6x+8) ?
The domain of f(x)=(x+1)/(x^2-6x+8) is x<2\lor 2<x<4\lor x>4
