Description
In y = x³, the output value is the input value multiplied by itself three times.
Characteristics
Concavity- The graph of y = x³ is concave down from (-∞, 0], and concave up from [0, ∞).
Decreasing/Increasing- The graph of y = x³ is increasing from (-∞, ∞).
Symmetry- The graph of y = x³ has odd symmetry because if rotated 180° around the origin, it would be the same graph.
