A Reflection with restpect to the origin of xy-plane. The graph of a function -f(-x) obtain reflect f(x) with respect to the origin of xy-plane. The graphs f(x) and -f(-x) are symmetrical with respect to the origin of xy-plane. The graph of absolute value of a function. The graph of a function |f(x)| obtain reflect a part of the graph f(x) below x-axis.
