Relationship Between the Graphs of a
Function and Its Inverse
• First we need to ascertain that the given graph corresponds to a one-to-one
function by applying the horizontal line test. If it passes the test, the
corresponding function is one-to-one.
GRAPHING INVERSE FUNCTIONS
• Given the graph of a one-to-one function, the graph of its inverse can be
obtained by reflecting the graph about the line y=x
