Absolute value matlab6/1/2023 Which is a reflection of #y = |2-x|# across the line #y=x#, as we would expect. Note that as #f(x)>=0# in the initial function, we must have #x>=0# for the inverse. If you don't care about about the inverse being a function, then we can just consider all the cases, similar to how we invert #y=x^2# by swapping #y# and #x# and then solving for #y#: #x = y^2 => y = +-sqrt(x)#. However, if #f(x)# maps more than one #x# value to a single #y#, then there is no way to know which #x#f^(-1)# should map #y# to. If #f# is a function which maps #x# to #y#, then #f^(-1)# is a function that maps #y# to #x#.
