domain of f(x)=(x-3)/(2x^2+10x)

domain

f (x) = \frac{x - 3}{2 x ^{2} + 10 x}

x < - 5 or - 5 < x < 0 or x > 0

Interval Notation

(- \infty, - 5) \cup (- 5, 0) \cup (0, \infty)

Solution steps

Find undefined (singularity) points:

x = 0, x = - 5

The function domain

x < - 5 or - 5 < x < 0 or x > 0

What is the domain of f(x)=(x-3)/(2x^2+10x) ?
The domain of f(x)=(x-3)/(2x^2+10x) is x<-5\lor-5<x<0\lor x>0
