domain of f(x)=(x^2+6x-27)/(x+9)

domain

f (x) = \frac{x ^{2} + 6 x - 27}{x + 9}

x < - 9 or x > - 9

Interval Notation

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

Solution steps

Find undefined (singularity) points:

x = - 9

The function domain

x < - 9 or x > - 9

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

\frac{4}{x ^{2} - 5 x + 6}

2 T - 3

f (x) = \frac{x}{2 + e ^{x}}

What is the domain of f(x)=(x^2+6x-27)/(x+9) ?
The domain of f(x)=(x^2+6x-27)/(x+9) is x<-9\lor x>-9
