Description
In y = ⅟x the out out is 1 divided by the input.
Characteristics
Concavity- The graph of y = ⅟x is concave down from (-∞, 0), and concave up from (0, ∞).
Decreasing/Increasing- The graph of y = ⅟x is decreasing from (-∞, 0), and decreasing again from (0, ∞).
Symmetry- The graph of y = ⅟x has odd symmetry because if rotated 180° around the origin, it would be the same graph.
Maximum: none
