domain of F(x)=(x-9)/(x^3+4x)

domain

F (x) = \frac{x - 9}{x ^{3} + 4 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{4}{e - e ^{\frac{2}{x + 2}}}

f (x) = \frac{∣ x - 1 ∣ - 2}{3 - ∣ x - 4 ∣}

e^{x + 1} + 1

250 \cdot e^{(0.0228 \cdot 8)}

f (x) = \frac{( x - 4 )}{x - 8}

What is the domain of F(x)=(x-9)/(x^3+4x) ?
The domain of F(x)=(x-9)/(x^3+4x) is x<0\lor x>0
