Given f:x -> (x-1)(x-3), for x ≤ c. Find the largest possible value of c for which the inverse of f exists.
I have sketched the graphs for f and inverse of f but that seems not that helpful. Can anyone help me? Thank you...
The question is asking you to restrict this quadratic so that it will have a inverse function. For something to have an inverse function it needs to be a one to one function. So think about how you could make that quadratic into a one to one function because at the moment it is not as the graph has more than 1 x value for each y value
