WebNo, all strictly growing or strictly decreasing functions have an inverse. If it is not strictly growing/decreasing, there will be values of f (x) where f (x) = f (y), x not equal to y. So, its inverse g would have two values for f (x), as g ( f (x) ) = x AND y, which is not possible for a function. An example of this is x^2.
