Suppose $f: A \to B$ is a function and $X \subseteq A$. Check all the statements that are true: A. $f^{-1}(f(X)) \subseteq X$ B. $f^{-1}(f(X)) \subseteq X$ if $f$ is 1-1 C. $f^{-1}(f(X)) \supseteq X$ D. $f^{-1}(f(X)) \supseteq X$ if $f$ is 1-1 E. None of the above

In Exercises 114–119, determine whether each statement is true or false. If the statement is false, make the necessary change(s) to produce a true statement. Prove that if $f$ and $g$ are even functions, then $f g$ is also an even function.
