probabilty densit function of a random variable is an even function. Note: is an even function if probability dense functions
fx (x) of a random variable X is an even function , meaning fx (x) = fx (-x) . Let Y = - x .show that X and Y are identically distributed

Why is the solution 1- FunctionX(-y) = FunctionX(y)? why are those two equal?

Can you please explain how to have the answer step by step?

please explain not just solve
