domain of f(x)=(x+2)/(7x^2+28x)

domain

f (x) = \frac{x + 2}{7 x ^{2} + 28 x}

x < - 4 or - 4 < x < 0 or x > 0

Interval Notation

(- \infty, - 4) \cup (- 4, 0) \cup (0, \infty)

Solution steps

Find undefined (singularity) points:

x = 0, x = - 4

The function domain

x < - 4 or - 4 < x < 0 or x > 0

f (x) = \frac{6 x}{2 x - 4}

f (x) = \frac{10}{t ^{2} - 100}

ln (- 2 x)

\frac{2 x ^{2} + 4 x + 2}{2 x ^{2} + 2 x + 1}

f (x) = 2 x^{2} - x + 1, (0 \leq x < 4)

What is the domain of f(x)=(x+2)/(7x^2+28x) ?
The domain of f(x)=(x+2)/(7x^2+28x) is x<-4\lor-4<x<0\lor x>0
