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

domain

f (x) = \frac{3}{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

2 x^{3} + 5

(3, - 5), (5, 9)

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

(- 3, 1), (5, - 3)

y = 52.947 x^{0.16}

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