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