domain of (x+5)/(x^2+3x-10)

domain

\frac{x + 5}{x ^{2} + 3 x - 10}

x < - 5 or - 5 < x < 2 or x > 2

Interval Notation

(- \infty, - 5) \cup (- 5, 2) \cup (2, \infty)

Solution steps

Find undefined (singularity) points:

x = 2, x = - 5

The function domain

x < - 5 or - 5 < x < 2 or x > 2

- 1 + 2 - x

f (x) = x - 11 + 5

- 2 + \frac{1}{x}

\frac{x}{( x + 2 ) ^{2}}

f (x) = f (x) = 1 - \frac{9}{x ^{2}}

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