Reflection
Reflection is
indicated by the graphs of these forms:
y = -f (x)
about x-axis
y = f (-x)
about y-axis
Graphs of the form
y = e-ax
Graphs of the form
y = -aex
Graph of
y = e2-x
This graph is
obtained by reflecting y = ex about the y-axis and translating it to
the right by 2 units.
Graph of
y = e2-x -
1
This graph is
obtained by translating the above graph by 1 unit in the direction of the
negative y-axis
Treatment of
reflection of logarithmic graphs is on the next page.
