domain of f(x)=(8-x)/(x+1)

domain

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

f (y) = \frac{1}{x}

\frac{sin ( 4 t ) - sin ( 2 t )}{cos ( 4 t ) - cos ( 2 t )}

f (x) = \frac{x}{x ^{2} - 225}

k (x) = \frac{x + 3}{x - 1}

f (x) = x^{3} - 12 x^{2} + 45 x - 54

What is the domain of f(x)=(8-x)/(x+1) ?
The domain of f(x)=(8-x)/(x+1) is x<-1\lor x>-1
