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

domain

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

x < - 2 or x > - 2

Interval Notation

(- \infty, - 2) \cup (- 2, \infty)

Solution steps

Find undefined (singularity) points:

x = - 2

The function domain

x < - 2 or x > - 2

f (x) = \frac{3 x}{8 - x}

\frac{e ^{2 x} - 1}{1 + e ^{2 x}}

3^{x} - 3

\frac{ln ( x ^{2} - x )}{- x}

f (x) = \frac{x + 5}{( x + 8 ) ( x - 9 )}

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