domain of f(x)= 2/((x-8)(x+7))

domain

f (x) = \frac{2}{( x - 8 ) ( x + 7 )}

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

Interval Notation

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

Solution steps

Find undefined (singularity) points:

x = 8, x = - 7

The function domain

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

f (x) = [- 2.2]

f (x) = \frac{x - 9}{x + 8}

f (x) = ln (x^{3} - 12 x)

\frac{x - 1}{x ^{2} + 5}

f (x) = \frac{16 - x ^{2}}{x - 3}

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