Solve the problem.Consider the graph of f(x) = , 0 ? x ? 1. What symmetry does the graph have? Is f its own inverse?

A. The graph of f has no symmetry. The function f is not its own inverse because there is no symmetry.
B. The graph of f is symmetric with respect to the line y = x. The function f is its own inverse because (f?f)(x) = x.
C. The graph of f is symmetric with respect to the y-axis. The function f is its own inverse because (f?f)(x) = x.
D. The graph of f is symmetric with respect to the y-axis. The function f is not its own inverse because (f?f)(x) = .
