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

domain

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

f (x) = \frac{5 t - 17}{6 + 4 t}

f (x) = \frac{x + 3}{x}

y = \frac{( 2 x - 1 )}{1 - 3 x}

f (x) = \frac{3}{8} x

f (x) = 1 + cos (x)

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