How is domain of the function f (x) = COS X restricted so that its inverse function exists? Drag a value or interval into each box to correctly complete the statements. The domain of f (x) = cos X is restricted to [0, It ] so that the inverse of the function exists. This means that all functional values of f (x) = cos " x are on the interval (0, IT) ( - 2 ' 2 (0, IT) [0, it ] (0, 2It) [0, 27]
