domain of (x^4+3x+x^2+1)/x

domain

\frac{x ^{4} + 3 x + x ^{2} + 1}{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) = 2 (y - 5)^{2} + 8

f (x) = 3 x + 1, 0 < x < 5

y = \frac{x - 8}{- 5}

(- 4 x^{2} + 3 x) (3 x - 5)

4 - 2 ∣ x ∣

What is the domain of (x^4+3x+x^2+1)/x ?
