domain of f(x)=(x+5)/(x^2+10x+25)

domain

f (x) = \frac{x + 5}{x ^{2} + 10 x + 25}

x < - 5 or x > - 5

Interval Notation

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

Solution steps

Find undefined (singularity) points:

x = - 5

The function domain

x < - 5 or x > - 5

\frac{5}{x + 2}

\frac{3 x - 5}{x ^{2} + x + 1}

f (x) = \frac{1}{x ^{3} - 5 x}

2 x^{2} + 7 x + 15

\frac{x + 1}{∣ x ∣ + 1}

What is the domain of f(x)=(x+5)/(x^2+10x+25) ?
The domain of f(x)=(x+5)/(x^2+10x+25) is x<-5\lor x>-5
