domain of f(x)=(x^2-3x+2)/(x^2-7x+6)

domain

f (x) = \frac{x ^{2} - 3 x + 2}{x ^{2} - 7 x + 6}

x < 1 or 1 < x < 6 or x > 6

Interval Notation

(- \infty, 1) \cup (1, 6) \cup (6, \infty)

Solution steps

Find undefined (singularity) points:

x = 6, x = 1

The function domain

x < 1 or 1 < x < 6 or x > 6

f (x) = \frac{x + 2}{x ^{2} - 121}

\frac{1}{2} x 25 - x^{2}

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

\frac{x - 9}{x ^{2} - 1}

\frac{x ^{2} + 2 x - 24}{x ^{2} - 2 x - 8}

What is the domain of f(x)=(x^2-3x+2)/(x^2-7x+6) ?
The domain of f(x)=(x^2-3x+2)/(x^2-7x+6) is x<1\lor 1<x<6\lor x>6
