domain of f(x)=(-8x^2)/((x-2)(x+5))

domain

f (x) = \frac{- 8 x ^{2}}{( x - 2 ) ( x + 5 )}

x < - 5 or - 5 < x < 2 or x > 2

Interval Notation

(- \infty, - 5) \cup (- 5, 2) \cup (2, \infty)

Solution steps

Find undefined (singularity) points:

x = 2, x = - 5

The function domain

x < - 5 or - 5 < x < 2 or x > 2

f (x) = 3 + 5 + 7 x

f (x) = \frac{4 x - 3}{2}

f (x) = 2^{x + 1} - 4

f (x) = \frac{x - 1}{x ^{2} - 2 x - 8}

\frac{x ^{3}}{2 ( 1 + x )}

What is the domain of f(x)=(-8x^2)/((x-2)(x+5)) ?
The domain of f(x)=(-8x^2)/((x-2)(x+5)) is x<-5\lor-5<x<2\lor x>2
