domain of f(x)=(x^2+15x+54)/(x+6)

domain

f (x) = \frac{x ^{2} + 15 x + 54}{x + 6}

x < - 6 or x > - 6

Interval Notation

(- \infty, - 6) \cup (- 6, \infty)

Solution steps

Find undefined (singularity) points:

x = - 6

The function domain

x < - 6 or x > - 6

f (x) = \frac{6}{- x + 3}

f (x) = 4 - 7 x^{2}

\frac{( x + 4 )}{x ^{2} - 9}

f (x) = y^{2} = x + 9

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

What is the domain of f(x)=(x^2+15x+54)/(x+6) ?
The domain of f(x)=(x^2+15x+54)/(x+6) is x<-6\lor x>-6
