domain of f(x)=(x-4)/(x+5)

domain

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

x < - 5 or x > - 5

Interval Notation

(- \infty, - 5) \cup (- 5, \infty)

Solution steps

Find undefined (singularity) points:

x = - 5

The function domain

x < - 5 or x > - 5

\frac{2 x}{x - 1}

f (x) = (2 \cdot x + 3) e^{(5 \cdot x)}

\frac{2}{( x + 1 ) ^{3}}

e^{x + 6}

5 x - 8

What is the domain of f(x)=(x-4)/(x+5) ?
The domain of f(x)=(x-4)/(x+5) is x<-5\lor x>-5
