domain of f(x)=(-19x+19)/(x^2-6x+8)

domain

f (x) = \frac{- 19 x + 19}{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

y = \frac{3}{4} x + 3

\frac{( x + 7 )}{( x ^{2} + 8 x - 9 )}

f (x) = ln (x - 2)

sin (x + π)

(7, - 7), at - x

What is the domain of f(x)=(-19x+19)/(x^2-6x+8) ?
The domain of f(x)=(-19x+19)/(x^2-6x+8) is x<2\lor 2<x<4\lor x>4
