domain of f(x)= 1/((x+7)(x+8))

domain

f (x) = \frac{1}{( x + 7 ) ( x + 8 )}

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

y = 1 - 2 x - 3 - 2 x - x^{2}

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

f (x) = \frac{x + 2}{7 x ^{2} + 28 x}

f (x) = \frac{6 x}{2 x - 4}

f (x) = \frac{10}{t ^{2} - 100}

What is the domain of f(x)= 1/((x+7)(x+8)) ?
The domain of f(x)= 1/((x+7)(x+8)) is x<-8\lor-8<x<-7\lor x>-7
