domain of f(x)=(x-8)/(x+7)

domain

f (x) = \frac{x - 8}{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

(3, 7), (6, 5)

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

f (x) = 4 - 2 x - 5

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

f (x) = 7 x^{2} + 7 x + 9

What is the domain of f(x)=(x-8)/(x+7) ?
The domain of f(x)=(x-8)/(x+7) is x<-7\lor x>-7
