Description
In y = |x|, the outut is the positive value of the input.
Characteristics
Concavity- The graph of y = |x| has no concavity.
Decreasing/Increasing- The graph of y = |x| is decreasing from (-∞, 0], and increasing from [0, ∞).
Symmetry- The graph of y = |x| has even symmetry because each side of the graph is a reflection of the other across the y-axis.
Maximum: none
Minimum: 0
