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) = \frac{x ^{2} + x}{x + 1}

y, y > 3 x + 9

\frac{x}{x ^{2} + 7 x}

- x^{2} + 7 x

What is the domain of (x^2+7)/(x+3) ?
