domain of f(x)=(80)/(x^2+10x)

domain

f (x) = \frac{80}{x ^{2} + 10 x}

x < - 10 or - 10 < x < 0 or x > 0

Interval Notation

(- \infty, - 10) \cup (- 10, 0) \cup (0, \infty)

Solution steps

Find undefined (singularity) points:

x = 0, x = - 10

The function domain

x < - 10 or - 10 < x < 0 or x > 0

f (t) = t + 1

y = 5 x + 5

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

4 x + 1

f (x) = x^{2} - 3 x + 2

What is the domain of f(x)=(80)/(x^2+10x) ?
The domain of f(x)=(80)/(x^2+10x) is x<-10\lor-10<x<0\lor x>0
