domain of f(x)=(9x)/(8(x+5))

domain

f (x) = \frac{9 x}{8 ( 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

f (x) = x - 10 + x + 2

f (x) = lo g_{\frac{1}{2}} (4 - x)

f (x) = x^{2} + 5 x + 20

f (x, y) = 4 - y^{2}

What is the domain of f(x)=(9x)/(8(x+5)) ?
The domain of f(x)=(9x)/(8(x+5)) is x<-5\lor x>-5
