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

domain

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

3 x^{4} - π x^{3} + 11 x - 4

lo g_{\frac{1}{2}} (x)

f (x) = x^{2} + 6 x + 9

∣ x - 3 ∣

f (x) = \frac{5 x}{x + 3}

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