Given:

The graph of an invertible function
f is given.

To find:

The value of
f^(-1)(-3).

Solution:

We know that, if the graph of an invertible function
f passes through the point (a,b), then the inverse function
f^(-1) passes through the point (b,a).

From the given graph it is clear that the graph of the function
f passes through the points
(-5,-3).

So, the inverse function
f^(-1) must be passes through the point
(-3,-5).

Therefore, the value of inverse function is
-5 at
x=-3. So, the value of
f^(-1)(-3) is
-5.
