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

domain

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

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

\frac{x}{x + 1} + \frac{x + 1}{x + 2}

f (x) = lo g_{3} (x^{2} - 7 x + 12)

2^{x + 2}

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

f (x) = \frac{( 3 x + 6 )}{( 10 x - 20 )}

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