domain of f(x)=(2x-5)/(x^2-5x+6)

domain

f (x) = \frac{2 x - 5}{x ^{2} - 5 x + 6}

x < 2 or 2 < x < 3 or x > 3

Interval Notation

(- \infty, 2) \cup (2, 3) \cup (3, \infty)

Solution steps

Find undefined (singularity) points:

x = 3, x = 2

The function domain

x < 2 or 2 < x < 3 or x > 3

- \frac{1}{x + 4} - 1

f (x) = x + 4 - 6

f (x) = \frac{x ^{2} - 25}{- 2 x ^{2} - 10}

f (x) = x^{4} - 36 x^{2}

f (x) = x^{4} - 6 x^{2} + 12

What is the domain of f(x)=(2x-5)/(x^2-5x+6) ?
The domain of f(x)=(2x-5)/(x^2-5x+6) is x<2\lor 2<x<3\lor x>3
