domain of (x^2-36)/(x+7)

domain

\frac{x ^{2} - 36}{x + 7}

x < - 7 or x > - 7

Interval Notation

(- \infty, - 7) \cup (- 7, \infty)

Solution steps

Find undefined (singularity) points:

x = - 7

The function domain

x < - 7 or x > - 7

f (x) = - 4 x^{2} - 20 x - 21

f (x) = x^{2} + x, x \geq \frac{1}{2}

g (x) = \frac{3 x}{4 - x}

\frac{7}{x ( x - 4 )}

\frac{9 x - 18}{x ^{2} - 5 x + 4}

What is the domain of (x^2-36)/(x+7) ?
The domain of (x^2-36)/(x+7) is x<-7\lor x>-7
