domain of f(x)=(2x)/(x^2+5x-36)

domain

f (x) = \frac{2 x}{x ^{2} + 5 x - 36}

x < - 9 or - 9 < x < 4 or x > 4

Interval Notation

(- \infty, - 9) \cup (- 9, 4) \cup (4, \infty)

Solution steps

Find undefined (singularity) points:

x = 4, x = - 9

The function domain

x < - 9 or - 9 < x < 4 or x > 4

What is the domain of f(x)=(2x)/(x^2+5x-36) ?
The domain of f(x)=(2x)/(x^2+5x-36) is x<-9\lor-9<x<4\lor x>4
