Inverse Functions
L14: Precalc. Review 1
Points on a
graph
are like a
stepping stone
from the
x
axis to the
y

axis, pictorially .…
Examples:
As long as we can hop from an
x
coordinate to just ____ ycoordinate
then the graph defines a function,
y(x).
We can summarize this by saying the graph passes the _________
linetest
, that is any vertical line that intersects the graph does so
only _______.

L14: Precalc. Review 2
The Inverse Graph is the reflection of a graph over the line ________,
where the coordinates of each point have been _________.
So if
(x,y)
is on a
Graph
, then _________ is on the
Inverse Graph
.
Hopping backwards from
y
axis
to
x
axis
using a
graph
is the ________ as
hopping forwards from
x
axis
to
y
axis
on an
inverse graph
. If the
inverse graph is not a function then…
1) We have ________ than
one
place to hop to.
2) A __________ line will cross the
inverse graph
more than once.
3) A __________ line will cross the
graph
more than once.
