domain of f(x)=(6x+5)/(x+1)

domain

f (x) = \frac{6 x + 5}{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

1 - x + 3

f (x) = x^{2} - 18 x + 86

f (x) = 4 x + 2 x^{2} + (x^{2} + 2 x)

90 - x^{2} + x

x^{2} + 2 x + 3 + 4

What is the domain of f(x)=(6x+5)/(x+1) ?
The domain of f(x)=(6x+5)/(x+1) is x<-1\lor x>-1
