domain of f(x)=(5x+25)/x

domain

f (x) = \frac{5 x + 25}{x}

x < 0 or x > 0

Interval Notation

(- \infty, 0) \cup (0, \infty)

Solution steps

Find undefined (singularity) points:

x = 0

The function domain

x < 0 or x > 0

3 x + 9

f (x) = x^{4}

y = 4 x - 3

\frac{( - 3 - 3 )}{( 5 - 2 )}

y = \frac{2}{3} x + c

What is the domain of f(x)=(5x+25)/x ?
The domain of f(x)=(5x+25)/x is x<0\lor x>0
