domain of f(x)=(2+x)/(x+1)

domain

f (x) = \frac{2 + 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

\frac{1 + x}{1 - e ^{- x}} - \frac{1}{x}

f (x) = \frac{x - 7}{x ^{2} - 49}

y = x^{2}

(- 10, - 1), (- 6, 7)

(- 1, 0), (- 3, - 4)

What is the domain of f(x)=(2+x)/(x+1) ?
The domain of f(x)=(2+x)/(x+1) is x<-1\lor x>-1
