| Graphs
and Inverses of Functions This is quite an indepth
section. You learn about reflections in the x-axis, y-axis, and the
line y=x. You also learn about the symmetry of these graphs and
special tests for the type of symmetry. This section also deals with
periodic function, stretching and shrinking graphs, and translating graphs.
The last part pertains to inverse functions and the lesser known HLT,
or Horizontal Line Test. This is used to see if a graph has an inverse.
