domain of f(x)=(-7-4x)/(7(-1-x))

domain

f (x) = \frac{- 7 - 4 x}{7 ( - 1 - x )}

x < - 1 or x > - 1

Interval Notation

(- \infty, - 1) \cup (- 1, \infty)

Solution steps

Find undefined (singularity) points:

x = - 1

The function domain

x < - 1 or x > - 1

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

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

(5 x - 2) + (4 x + 1)

f (x) = - 4 x - 1

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

What is the domain of f(x)=(-7-4x)/(7(-1-x)) ?
The domain of f(x)=(-7-4x)/(7(-1-x)) is x<-1\lor x>-1
