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

domain

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

x^{2} + 7, x \geq - 5

\frac{2 x - 6}{x ^{2} - 6 x}

f (x) = 30 - 6 x

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

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