domain of f(x)=(x-8)/(x^2+14x+45)

domain

f (x) = \frac{x - 8}{x ^{2} + 14 x + 45}

x < - 9 or - 9 < x < - 5 or x > - 5

Interval Notation

(- \infty, - 9) \cup (- 9, - 5) \cup (- 5, \infty)

Solution steps

Find undefined (singularity) points:

x = - 5, x = - 9

The function domain

x < - 9 or - 9 < x < - 5 or x > - 5

y = - 2 x + 3

(x - 7)^{2}

f (x) = ln (2 x + 3)

f (x) = x^{4} - 98 x^{2} + 2401

9 - 3^{x}

What is the domain of f(x)=(x-8)/(x^2+14x+45) ?
The domain of f(x)=(x-8)/(x^2+14x+45) is x<-9\lor-9<x<-5\lor x>-5
