domain of f(x)=(x^2+3)/(x+2)

domain

f (x) = \frac{x ^{2} + 3}{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) = (x + 1) (x - 4)^{2}

m

f (x) = lo g_{b} (x)

\frac{1}{x - 6}

f (x) = x^{2} - 4 x - 12

What is the domain of f(x)=(x^2+3)/(x+2) ?
The domain of f(x)=(x^2+3)/(x+2) is x<-2\lor x>-2
