Given the table of values of a function, determine whether it is invertible or not.

Problem

f is a finite function whose domain is the letters a to e. The following table lists the output for each input in f's domain.

f, left parenthesis, x, right parenthesis124816
Build the mapping diagram of f by dragging the endpoints of the segments in the graph below so that they pair each domain element with its correct range element.
Then, determine if f is invertible.
