domain of f(x)=(8x+80)/(10x)

domain

f (x) = \frac{8 x + 80}{10 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

y = - 3 x

3 - 4 x

f (x) = e^{3 x} + 1

x^{3} - 3 x^{2} - 4 x + 12

f (x) = 2 x^{3} + 3 x^{2} - 180 x

What is the domain of f(x)=(8x+80)/(10x) ?
The domain of f(x)=(8x+80)/(10x) is x<0\lor x>0
