domain of f(x)=(x+3)/(x^2+3x+2)

domain

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

x < - 2 or - 2 < x < - 1 or x > - 1

Solution steps

Find undefined (singularity) points:

x = - 1, x = - 2

The function domain

x < - 2 or - 2 < x < - 1 or x > - 1

(2.1) (- 3.6)

6 y - 8 x = 54

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

f (x) = \frac{( x + 1 )}{x ^{2} - 4}

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

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