domain of f(x)=(3x+15)/(5x)

domain

f (x) = \frac{3 x + 15}{5 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

(x - 2) (x + 2) (x + 4)

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

f (x) = \frac{( 8 e ^{x} )}{( e ^{x} - 2 )}

cos (2 t)

f (x) = 5 x + 7

What is the domain of f(x)=(3x+15)/(5x) ?
The domain of f(x)=(3x+15)/(5x) is x<0\lor x>0
