domain of f(x)=(x^2-3x-28)/(x+2)

domain

f (x) = \frac{x ^{2} - 3 x - 28}{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

3 x^{2} + 1

f (x) = 3 x^{4} - 2 x^{2} + 5

\frac{1}{5 x - 20}

f (x) = ln (2 x) - 3

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

What is the domain of f(x)=(x^2-3x-28)/(x+2) ?
The domain of f(x)=(x^2-3x-28)/(x+2) is x<-2\lor x>-2
