domain of (x^2-7)/(x+3)

domain

\frac{x ^{2} - 7}{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) = x^{2} - 6 x + 1

f (x) = 8 (x + 10)

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

3 cos (x)

(x - 6)^{3}

What is the domain of (x^2-7)/(x+3) ?
The domain of (x^2-7)/(x+3) is x<-3\lor x>-3
