domain of f(x)=(2x+1)/(x+3)

domain

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

x < - 3 or x > - 3

Interval Notation

(- \infty, - 3) \cup (- 3, \infty)

Solution steps

Find undefined (singularity) points:

x = - 3

The function domain

x < - 3 or x > - 3

f (x) = \frac{x - 1}{4 + x ∣ x ∣}, x > - 2

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

f (x) = (3 x - 4) - (2 - x)

\frac{2 x}{x + 3}

f (x) = \frac{1}{1.5 x - 6.2 x ^{2}}

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