domain of (55x^3+15x^2-5x)/(5x)

domain

\frac{55 x ^{3} + 15 x ^{2} - 5 x}{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

\frac{x}{x ^{2} + 2}

f (x) = 15 - 2 x

f (x) = \frac{2 x - 1}{- 3 x + 1}

f (x) = 2 x^{2} + 6

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

What is the domain of (55x^3+15x^2-5x)/(5x) ?
The domain of (55x^3+15x^2-5x)/(5x) is x<0\lor x>0
