domain of f(x)=(x^2+2)/(x+4)

domain

f (x) = \frac{x ^{2} + 2}{x + 4}

x < - 4 or x > - 4

Interval Notation

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

Solution steps

Find undefined (singularity) points:

x = - 4

The function domain

x < - 4 or x > - 4

f (x) = 8 - 4 x

f (x) = 3 x^{3}

f (x) = \frac{4 x}{x ^{2} + 1} + 98.6

f (x) = x^{2} (x - 5) (x - 3)

f (x) = 10 x - 9

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