A Reflection the graph of a function with restpect to the x-axis. The graph of a function -f(x) obtain reflect f(x) with respect to the x-axis. The graphs f(x) and -f(x) are symmetrical with respect to the x-axis. A Reflection the graph of a function with restpect to the y-axis. The graph of a function f(-x) obtain reflect f(x) with respect to the y-axis. The graphs f(x) and f(-x) are symmetrical with respect to the y-axis.
