Given:
The graph of an invertible function
is given.
To find:
The value of
.
Solution:
We know that, if the graph of an invertible function
passes through the point (a,b), then the inverse function
passes through the point (b,a).
From the given graph it is clear that the graph of the function
passes through the points
.
So, the inverse function
must be passes through the point
.
Therefore, the value of inverse function is
at
. So, the value of
is
.
