Cube Root
f(x) = ∛x
Overview
The cube root is defined for all real numbers, unlike the square root.
Domain
(-∞, +∞)
Range
(-∞, +∞)
Symmetry
Odd
Key Properties
1
Defined for all real x
2
Odd function (rotational symmetry)
3
Inflection point at origin
4
Vertical tangent at x = 0
Key Insight
Unlike √x, ∛x handles negative inputs: ∛(-8) = -2. This makes it useful for signed quantities.
