domain of (x+8)/(x^2+x-56)

domain

\frac{x + 8}{x ^{2} + x - 56}

x < - 8 or - 8 < x < 7 or x > 7

Interval Notation

(- \infty, - 8) \cup (- 8, 7) \cup (7, \infty)

Solution steps

Find undefined (singularity) points:

x = 7, x = - 8

The function domain

x < - 8 or - 8 < x < 7 or x > 7

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

f (x) = \frac{5}{x - 1}

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

7, - 4

y = 2 x, (1, 2)

What is the domain of (x+8)/(x^2+x-56) ?
The domain of (x+8)/(x^2+x-56) is x<-8\lor-8<x<7\lor x>7
