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

domain

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

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

(5, - 1), (6, - 6)

x - \frac{1}{x}

y = - x^{2} - 2 x + 1

2 - x

f (x) = x^{2} - 4 x + 7

What is the domain of f(x)=-9/(2x^{2/3)} ?
The domain of f(x)=-9/(2x^{2/3)} is x<0\lor x>0
