domain of f(x)=((x^2-4))/((x+3))

domain

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

x < - 3 or x > - 3

Interval Notation

(- \infty, - 3) \cup (- 3, \infty)

Solution steps

Find undefined (singularity) points:

x = - 3

The function domain

x < - 3 or x > - 3

f (x) = \frac{1 + x}{x - 1}

\frac{x ^{2} - 4}{x - 4}

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

f (x) = x - 2 + 4 - x

f (x) = \frac{x - 9}{x ^{2} - 16}

What is the domain of f(x)=((x^2-4))/((x+3)) ?
The domain of f(x)=((x^2-4))/((x+3)) is x<-3\lor x>-3
