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

domain

f (x) = \frac{( 2 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

\frac{7 b - 14 b ^{2}}{42 b ^{2} - 21 b}

x^{2} + 5

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

f (x) = \frac{ln ( x )}{ln ( x - 1 )}

f (x) = ln (1 + ln (x))

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