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

domain

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

R (x) = (\frac{( x + 2 )}{( x + 5 )})

y = x^{4} - 4 x^{3} + 314 x^{2} - 79 x + 2

f (x) = \frac{1}{2 + 3}

y = \frac{3 x}{8 - x}

f (x) = 10 e^{- x} cos (x)

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