Given:
The graph of an invertible function <em> </em>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
.
