domain of f(x)= x/(x^2+12x+35)

domain

f (x) = \frac{x}{x ^{2} + 12 x + 35}

x < - 7 or - 7 < x < - 5 or x > - 5

Interval Notation

(- \infty, - 7) \cup (- 7, - 5) \cup (- 5, \infty)

Solution steps

Find undefined (singularity) points:

x = - 5, x = - 7

The function domain

x < - 7 or - 7 < x < - 5 or x > - 5

f (x) = 1 - x ln (x + 2)

f (x, y) = x^{2}

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

f (x) = \frac{2 x ^{2} - 6 x + 4}{3 x - 5}

What is the domain of f(x)= x/(x^2+12x+35) ?
The domain of f(x)= x/(x^2+12x+35) is x<-7\lor-7<x<-5\lor x>-5
