domain of (5+2x)/(1+x)

domain

\frac{5 + 2 x}{1 + x}

x < - 1 or x > - 1

Interval Notation

(- \infty, - 1) \cup (- 1, \infty)

Solution steps

Find undefined (singularity) points:

x = - 1

The function domain

x < - 1 or x > - 1

\frac{3 x + 4}{6 x - 1}

f (x) = \frac{5 x ^{2}}{x ^{2} - 4}

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

(2, 8), (4, 5)

f (x) = ln (x^{2} - 4)

What is the domain of (5+2x)/(1+x) ?
The domain of (5+2x)/(1+x) is x<-1\lor x>-1
