domain of f(x)=(19x)/(x+20)

domain

f (x) = \frac{19 x}{x + 20}

x < - 20 or x > - 20

Interval Notation

(- \infty, - 20) \cup (- 20, \infty)

Solution steps

Find undefined (singularity) points:

x = - 20

The function domain

x < - 20 or x > - 20

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

\frac{x ^{2} + 2 x - 3}{x + 1}

f (x) = \frac{x + 10}{6 + x}

x = y - 4

f (x) = ln (x^{2} - 2 ∣ x ∣ + 2)

What is the domain of f(x)=(19x)/(x+20) ?
The domain of f(x)=(19x)/(x+20) is x<-20\lor x>-20
