domain of f(x)=(2x+12)/(3x)

domain

f (x) = \frac{2 x + 12}{3 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

f (x) = arctan (1 + e^{- r^{2}})

f (x) = 9 - 3 x^{2}

(0, 16), (7, 10)

f (x) = 3 (5^{x})

- \frac{5}{6}

What is the domain of f(x)=(2x+12)/(3x) ?
The domain of f(x)=(2x+12)/(3x) is x<0\lor x>0
