It was given that the points and
are on the graph of the function
.
If is the inverse function of
, then
will take the y-values as inputs and give the x-values as outputs.
Hence we will have the ordered pairs and
on g.
In other words, f and g are symmetric about the line . This implies that when we reflect the points
and
in the line
we will obtain
and
.
This point must lie on g.
