Description
In the function y = x, the input is the same as the output.
Characteristics
Concavity- The graph of y = x is neither concave up nor concave down due to the graph being linear.
Decreasing/Increasing- The graph of y = x is always increasing, so the interval where it is increasing is from (-∞, ∞).
Symmetry- The graph of y = x has odd symmetry because if rotated 180° around the origin, it is the same graph.
Maximum: none
Minimum: none
