domain of f(x)= 4/((4+4x))

domain

f (x) = \frac{4}{( 4 + 4 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{7 + x}{e ^{c o s (x)}}

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

sin (x), - \frac{π}{2} < x < \frac{π}{2}

f (x) = \frac{- 12 ( 3 x ^{2} + 4 )}{( x ^{2} - 4 ) ^{3}}

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

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