domain of f(x)=(x+12)/(x^2+9x-22)

domain

f (x) = \frac{x + 12}{x ^{2} + 9 x - 22}

x < - 11 or - 11 < x < 2 or x > 2

Interval Notation

(- \infty, - 11) \cup (- 11, 2) \cup (2, \infty)

Solution steps

Find undefined (singularity) points:

x = 2, x = - 11

The function domain

x < - 11 or - 11 < x < 2 or x > 2

f (x) = \frac{x}{( x + 4 )}

x^{2} - 1 + 15

\frac{x - 5}{x ^{2} - 2 x - 35}

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

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

What is the domain of f(x)=(x+12)/(x^2+9x-22) ?
The domain of f(x)=(x+12)/(x^2+9x-22) is x<-11\lor-11<x<2\lor x>2
