domain of f(x)=-1/(2(x+1))+3

domain

f (x) = - \frac{1}{2 ( x + 1 )} + 3

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) = e^{a r c t a n (x)}

y, y \leq - x

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

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

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

What is the domain of f(x)=-1/(2(x+1))+3 ?
The domain of f(x)=-1/(2(x+1))+3 is x<-1\lor x>-1
