domain of f(x)=((x*x+1))/((x+2))

domain

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

x < - 2 or x > - 2

Interval Notation

(- \infty, - 2) \cup (- 2, \infty)

Solution steps

Find undefined (singularity) points:

x = - 2

The function domain

x < - 2 or x > - 2

f (x) = \frac{- x + 5}{- 4 x + 8}

f (x) = \frac{9}{8 x + 9}

g (x) = \frac{x}{x ^{2} + 36}

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

\frac{900}{56}

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