domain of (x^2-5x+4)/(x+1)

domain

\frac{x ^{2} - 5 x + 4}{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

- x^{3} + 3 x^{2} + 10 x

f (x) = - 2 x + 4 - 1

0 = 6.3 + 0 (1.188 - 0) \frac{1}{2} x (1.188 - 0)^{2}

3 x 2 x^{2} + 3

What is the domain of (x^2-5x+4)/(x+1) ?
The domain of (x^2-5x+4)/(x+1) is x<-1\lor x>-1
